Animal breeding is the practice of producing improved breeds of domesticated animals by improving their genotypes through selective mating. Out-breeding is a type of animal breeding.

Out-breeding is the practice of breeding unrelated animals which may be between individuals of same breed or different breeds or different species.

They are of three types :

• Out-crossing is the practice of mating of animals within the same breed which do not have common ancestors on either side of their pedigree upto 4-6 generations. The offspring of such a cross is called outcross.
• Cross-breeding is the method of crossing superior males of one breed with superior females of another breed. Example is Hisardale, a new breed of sheep developed in Punjab by crossing Bikaneri ewes and Marino rams.

• Interspecific hybridization is the practice of mating of males and females of two different species. One of the examples is Mule, which is a hybrid produced by performing a cross between female horse (mare) and male donkey.

So, the correct answer is 'b'.
