The Correct Option is C

Solution and Explanation

In situ (on site) conservation is conservation and protection of the whole ecosystem and its biodiversity at all levels, in order to protect the threatened species. Two in situ methods are being used to save biodiversity viz., hot spots and protected areas. Protected areas include national parks, sanctuaries, biosphere reserves and sacred groves. Ex situ (off site) conservation is conservation of selected rare plants/animals in places outside their natural homes. Ex situ conservation includes offsite collections, seed banks, gene banks, in vitro fertilization, cryopreservation techniques and tissue culture.

Biodiversity and Conservation

The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.

Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
