Verified Solution

Answer & Solution

Correct Answer

(C) I, II, III, IV

Step-by-step Solution

Detailed explanation

(C) I, II, III, IV,
The advanced ex situ involves the conservation of genetic resources of species away from their area of origin or development. This strategy is aimed to conserve more genetic material in less area. The various ways in which ex situ conservation can be achieved are tissue culture, cryopreservation, gene bank and off-site collection. All statements are correct.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
