• A. In situ conservation of biodiversity
• B. In situ cryo-conservation of biodiversity
• C. In situ conservation by sacred groves
• D. Advanced ex-situ conservation of biodiversity

Answer 1

The correct option is D

Advanced ex-situ conservation of biodiversity

The correct option is D.

Explanation of Correct option:

1. Ex-situ Conservation is a method of conserving living species in artificial habitats that reflect their natural living habitats.
2. Examples include aquariums, botanical gardens, cryopreservation, DNA banks, zoos, etc.
3. Cryopreservation is the use of very low temperatures to preserve the cells and tissues that are structurally intact.
4. Cryopreservation of gametes involves keeping oocytes, spermatozoa, tissues, embryos, etc. in extremely cold temperatures without affecting the cell's viability

Explanation of Incorrect option:

Option A:

1. In situ conservation of biodiversity is a method of conserving living species in their natural habitats and environment.
2. E.g. biosphere reserves, national parks, wildlife sanctuaries, etc.

Option B:

1. Cryopreservation is the use of very low temperatures to preserve the cells and tissues that are structurally intact.
2. It is an example of ex situ conservation.

Option C:

1. Sacred groves are forest fragments protected by religious communities having a significant religious connotation for the protecting community.
2. They are an example of in-situ conservation.

Final answer:

Cryopreservation of gametes of threatened species in viable and fertile conditions can be referred to as advanced ex-situ conservation of biodiversity.
