Solution
The correct option is B Genetic erosion
Genetic erosion is a process whereby an already limited gene pool of an endangered species of plant or animal diminishes even more, when individuals from the surviving population die off without getting a chance to meet and breed with others in their endangered low population. The term is sometimes used in a narrow sense, such as when describing the loss of particular alleles or genes, as well as being used more broadly, as when referring to the loss of varieties or even whole species.
Genetic erosion occurs because each individual organism has many unique genes, which get lost when it dies without getting a chance to breed.
