   Correct answer: A) Cryopreservation of gametes and seeds in cryogenic gene banks

   Ex-situ conservation involves the preservation of biological diversity components outside their natural habitats (e.g., cryogenic gene banks, botanical gardens, zoological gardens, seed banks). In-situ conservation protects species within their natural ecosystems (national parks, nature reserves, sanctuaries).
