The correct option is C Out crossing
The mating of two varieties of a cattle breed Red Dane which have no common ancestors on either side of their pedigree up to 4-6 generations produces good quality offsprings and offspring of such cross is called as an outcross. This method used for animals that are below average in productivity in milk production, the growth rate in cattle, etc. It also helps to overcome inbreeding depression.
