Captive breeding: a) has allowed for the reintroduction of many species to areas from which they had disappeared. b) does not require an understanding of the behavior and ecological niche of the target species. c) can work for animals but is generally not used for endangered plants. d) is the main conservation technique used to try to save endangered species from extinction.

Option-D

Explanation:

Captive breeding or breeding in the captivity is the conservation technique employed by the government to conserve nature.

Captivity breeding is also known as the captive propagation of animals in which animals are kept either in their natural habitat (ex-situ conservation) or in artificial conditions like in zoos where condition similar to the habitat of animal are created.

The breeding programme aims at conserving the natural habitat of the animals to prevent the endangered species from extinction. The endangered species are at risk of extinction due to loss of fragmentation, pollution, predation and others.

Thus, Option-d is the correct answer.
