The correct option is B All of these

Out-breeding is the breeding of unrelated animals.

It is of the following types.

• Out-crossing: Mating between individuals of the same breed but having no common ancestors for 4 - 6 generations.
• Cross- breeding: Mating between different breeds. It allows the desirable qualities of two different breeds to be combined.
• Interspecific hybridisation: The male and female animals of two different but related species are mated. Mule is an interspecific hybrid obtained by crossing a female horse and a male donkey.
