Correct answer: B. Helps overcome inbreeding depression
Explanation: Out-crossing, the mating of unrelated animals of the same breed, is the best method to overcome inbreeding depression in animals that are not performing well.
Different fish species occupy different feeding depths in the same pond without competing for food: Catla feeds near the surface, Rohu in the middle zone, and Mrigal or common carp at the bottom - letting a single pond support far more total fish than one species alone.
