Options

  1. ACryopreservation of gametes
  2. BIdentification of biodiversity hotspots
  3. CMaintenance of sacred groves
  4. DEstablishment of biosphere reserves

Correct answer

A. Cryopreservation of gametes

Step-by-step solution

Ex-situ conservation involves the protection of biological diversity outside their natural habitats. Cryopreservation of gametes is an advanced ex-situ conservation method where gametes of threatened species are preserved in viable and fertile conditions for long periods using liquid nitrogen at -196^ C . Biodiversity hotspots, sacred groves, and biosphere reserves are all examples of in-situ conservation strategies, where species are protected within their natural habitats. Answer: Cryopreservation of gametes
