Correct option is A)
Fertilization of the ovum and its subsequent implantation is referred to as conception or pregnancy. Prevention of conception is called contraception.
Oral contraceptives (birth control pills) can be taken to change the hormonal balance of the body so that the ovum is not released from the ovary.
The pills may contain combinations of the hormones estrogen and progestins or progestins alone.
Combinations of estrogen and progestins prevent pregnancy by inhibiting the release of the hormones luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland, which further prevents ovulation.
Thus, the correct answer is option A.
