On the basis of status of development, how are resources classified?

The correct answer is D. By status of development resources are grouped as potential resources, found in a region but not yet used; developed resources, surveyed and in use; stock, which exists but cannot be used for want of technology; and reserves, the part of the stock that can be drawn on in future with present technology. The Bunder diamond ground of Chhatarpur is a good example of a potential resource, while the Majhgawan mine of Panna is a developed one.

Option A, biotic and abiotic, is the classification by origin, that is living and non living. Option B, renewable and non renewable, is the classification by exhaustibility, the one most candidates remember first. Option C, individual, community, national and international, is the classification by ownership. Four bases of classification, four sets of names: learning them as a table prevents exactly this mix up.
