The correct option is B Hybridisation of cattle
Multiple ovulation and embryo transfer technology (MOET) is a method used for the hybridization of the cattle. In this method, a hormone (with FSH-like activity) is given to the cow for inducing follicular maturation and superovulation instead of one egg, which they usually give per cycle, they produce 6-8 eggs. The cow is either mated with the best bull or artificially inseminated. The embryos at 8-32 cell stage are recovered and transferred to surrogate mothers. The genetic mother is available for another superovulation. MOET has been done in cattle, sheep, rabbits, buffaloes, mares, etc. High milk giving breeds of females and high quality (lean meat with less lipid) meet giving bulls have been bred successfully to obtain better breed in a short time.
