What is the total approved cost of the GalaxEye multisensor satellite project?

The correct answer is Rs 63.84 crore, the financial support agreed under the Research Development and Innovation Fund and routed through optionally convertible debentures rather than paid out as a simple grant. Keep it apart from the other money figure in the same announcement, the total approved cost of the project, which is far larger; a question will often place the two side by side to see whether a candidate has confused the support with the whole outlay. Options A and C are the same digits rearranged, a trap that works precisely because the figure carries two decimal places and is easy to garble under time pressure. Option D is a round-looking amount that appears nowhere in the announcement. The safest habit is to read such a figure once as a whole number of crore and once as its decimal part.

The correct answer is Synthetic Aperture Radar and electro-optical imaging, and the name of the technology is itself the clue, since Opto stands for the optical sensor and SAR for the radar. The two are put on one platform because their weaknesses do not overlap: optical imaging gives rich visual detail but is defeated by cloud cover and by darkness, while radar works irrespective of daylight and can image through cloud. Fusing the two data streams therefore yields a fuller and less interrupted view of the ground, which is what makes wide-area surveillance, detection of people and vehicles and classification of targets possible in all weather. Options B, C and D list real remote-sensing techniques, but none of them is the pair named here, and option D also includes sonar, which works in water rather than from orbit.

The correct answer is TRL-6 to TRL-9. Technology Readiness Level is a scale for how far a technology has travelled from an idea towards routine use, and the stretch named here is the late one: a system already demonstrated in conditions close to the real environment has to be engineered, tested and validated until it is proven in actual service. The Board describes its role in exactly those terms, as support through the critical stages between advanced development and deployment, with commercialisation as the eventual aim. Options A and B describe earlier stages, where the work is closer to laboratory research than to flight hardware, and a candidate who assumes that public funding always goes to early research will be drawn to them. Option D stops short of the top of the scale and so does not match the stated goal of reaching deployment.

The correct answer is Optionally Convertible Debentures, usually shortened to OCD. The Technology Development Board is routing its support to Ubifly Technologies through this instrument, which is a form of debt that the holder has the option of converting into equity shares of the company after an agreed period. Option A is wrong because the release does not describe the money as a grant; the choice of a convertible instrument is precisely what distinguishes this kind of deep-tech support from a subsidy. Option B is wrong because sovereign green bonds are raised by the government in the market for environment-related spending and have nothing to do with this approval. Option D is wrong because viability gap funding is a support mechanism used mainly in infrastructure projects. The Research Development and Innovation Fund, from which this support comes, is a Rs 1 lakh crore pool aimed at private-sector-led technology development.

The correct answer is a three-seater zero-emission advanced air mobility aircraft. The release describes the e200X as configured for one pilot and two passengers, with a targeted range of 110 km and an ideal speed of 160 kmph, and with a landing gear built for both conventional and vertical landing so that it can operate out of relatively small spaces. Option A is wrong because the aircraft is electrically powered and seats three, not two, and it is not described as a trainer. Option C is wrong because the configuration explicitly includes a pilot on board along with two passengers, so it is not an unmanned platform. Option D is wrong on every count, as the e200X is a small electric machine and not a turboprop airliner. Its indigenous elements include vertical rotors, forward propellers, proprietary flight-control algorithms, power-distribution controllers and battery packs with integrated cooling.
