Litmus is a natural indicator obtained from lichens, which are a partnership between an alga and a fungus, and in a neutral solution it shows a purple colour.

A haloalkane carries a halogen atom - fluorine, chlorine, bromine or iodine - bonded to a carbon chain, so no oxygen appears in its functional group at all.

Cyclohexane is a closed ring of six carbon atoms joined by single bonds, and each carbon carries two hydrogen atoms, which gives C6H12.

The alkene series begins at two carbon atoms, so its first member is ethene, C2H4, and its second member is propene, C3H6.

C3H4 is propyne, and it fits the alkyne general formula CnH2n-2 when n equals 3. Alkynes are unsaturated hydrocarbons that carry at least one carbon-to-carbon triple bond, and the first member of the family is ethyne, C2H2, better known as acetylene and burnt with oxygen in welding torches.

Put n equal to 3 in the alkyne general formula CnH2n-2 and the result is C3H4, which is propyne, the second member of the alkyne series.

An alkene is an unsaturated hydrocarbon in which two carbon atoms are joined by a double bond, so the carbon-to-carbon double bond is its identity.

Alkanes are saturated hydrocarbons, so every bond between two carbon atoms is a single bond and all the remaining valencies are filled by hydrogen.

The d-block sits in the middle of the periodic table, bridging the s-block on the left and the p-block on the right.

The halogens are placed in Group 17 of the modern periodic table. This family has five members - fluorine, chlorine, bromine, iodine and astatine.

The SETU NSP App brings scholarship services onto a single platform, and lending has nothing to do with the Pre-Matric and Post-Matric Scholarships it serves.

The correct answer is the Ministry of Social Justice and Empowerment, through its Department of Social Justice and Empowerment, which launched the app in April 2026.

The app carries this name together with the National Scholarship Portal and belongs to the Ministry of Social Justice and Empowerment, serving beneficiaries of the Pre-Matric and Post-Matric Scholarships for Scheduled Castes and Other Backward Classes.

Phase-II follows the two-year Phase-I pilot and is designed to test the methods in varied conditions so that region-specific Standard Operating Procedures can be established.

For decades these two have been the mainstay of post-harvest pest control in the country’s grain reserves, and their widespread, repeated use is what pushed pest resistance to 72 to 100 per cent in key states while raising fumigation cycles and costs.

The correct answer is ICAR-CIPHET, Ludhiana, the Central Institute of Post-Harvest Engineering and Technology, which will carry out the two-year Phase-I of the project on alternatives to chemical fumigation in wheat and rice.

Trishakti Manthan was the event organised as part of the Silver Jubilee, featuring addresses by the Chief of Defence Staff and by the Chief of Integrated Defence Staff, and it is not described as a standing institutional mechanism of the kind listed in the other options.

Under this theme HQ IDS organised Trishakti Manthan, released a Silver Jubilee Book and a film on its milestones, and conferred CDS Unit Citations on personnel.

HQ IDS was established in New Delhi on that date, and the day is observed every year as Tri-Service Day; the organisation therefore completed 25 years and celebrated its Silver Jubilee under the theme of future readiness through jointness and integration.

The correct answer is Keshav Chandra, Secretary, Ministry of Mines, who launched the auction virtually for the grant of a Composite Licence.
