Captive breeding is the process of maintaining plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by human activities. The activities which pose threat include habitat loss, fragmentation, over-hunting or fishing, pollution, predation, disease, and parasitism. The objective of many captive populations is to hold similar levels of genetic diversity to what is found in wild populations.

A) IUCN stands for the International Union for Conservation of Nature and Natural Resources.

In a reciprocal cross, a male expressing the trait of interest will be crossed with a female not expressing the trait or vice versa. The method can be used for the protection of white lions from getting extinct as some white lions will be produced in the progeny. There are fewer than 12 White Lions in the wilds of their endemic habitat. The need for conserving white lions is extreme now.

Water pollution is the mixing of contaminants to the water bodies (e.g., lakes, rivers, oceans, aquifers and groundwater) which changes the desired quality of water. Water pollution affects the entire biosphere, plants and organisms living in these bodies of water.

Water pollution affects the entire biosphere, plants and organisms as all the life forms depend on water for their survival. In almost all cases, the effect is damaging not only to individual species and population but also to the natural biological communities. 

Wildlife sanctuary is a place where animals live in a natural habitat. The place where animals live in artificial habitat is known as zoo. 

Reforestation can be defined as the establishment of forest by planting trees in those areas where there is no previous forest cover. This can be done either naturally by means of natural seeding or we can go for artificial methods in which the trees are planted or seeding is done directly.

The Gir national park and wildlife sanctuary are located at Gujarat. Kanha national park and Bandhavgarh national park is located in Madhya Pradesh. Sariska wildlife sanctuary and Ranthambore national park and wildlife sanctuary are located in Rajasthan. Mudumalai national park and wildlife sanctuary are located in Tamil Nadu. Thus, the correct answer is option B.

Wildlife represents the uncultivated or undomesticated species. They have a wide gene pool. The cultivated plants and domesticated animals have a narrow gene pool because these organisms have been selected by man over a period of thousands of year. Further, the cultivated plants and domesticated animals grow in protected environments. The uncultivated plants and nondomesticated animals, on the other hand, grow in natural surroundings in conjunction with disease-causing organisms and depend on the naturally evolved defense mechanisms. These organisms have evolved disease resistance, mechanisms and are a rich source of disease resistance germplasm.
