The destruction of wildlife can have various negative effects, but one important consequence is that wild genes of disease resistance may not be obtained. Wild populations often carry genetic diversity that can be crucial for developing disease-resistant strains of plants and animals. The loss of wildlife can limit the genetic resources available for breeding programs aimed at disease resistance.
So, the correct option is (A): Wild gene of disease resistance will not be obtained

Among ‘The Evil Quartet’, which one is considered the most important cause driving extinction of species?
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.
