Answer :
Final answer:
In artificial insemination, semen should ideally be deposited in the uterine horn, which is near the oviduct, the typical site of fertilization. Thus, option A is correct.
Explanation:
When performing artificial insemination in cattle or horses, the semen should be deposited into the uterine horn for best fertility. Thus, option A is correct. This is because the uterine horn is closest to the site of fertilization, which typically occurs in the oviduct (also known as the fallopian tube in humans). Fertilization involves the union of an egg from the female with sperm from the male, which enters the reproductive tract through the vagina. After ovulation, the egg is present in the oviduct, where it may be fertilized before moving to the uterus.
