Best answer
The correct option is (d) Inbreeding

Explanation: Inbreeding increases homozygosity, thus inbreeding is necessary if we want to evolve a pure line in any animal. Inbreeding also exposes harmful recessive genes that are eliminated by selection. It also helps in the accumulation of superior genes and the elimination of less desirable genes.
