I had been asked this question in an international level competition.

Answer 1

Correct option is (a) Mating between animals of unrelated species

Easiest explanation: Inbreeding is the mating between the animals of the same breed having common ancestors up to 4-6 generations. Inbreeding increases homozygosity. It is also responsible for the elimination of undesirable characters and it causes inbreeding depression.
