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.
