Options

  1. AA-IV, B-II, C-III, D-I
  2. BA-I, B-III, C-II, D-IV
  3. CA-IV, B-III, C-II, D-I
  4. DA-III, B-IV, C-I, D-II

Correct answer

C. A-IV, B-III, C-II, D-I

Step-by-step solution

Barrier methods prevent the physical meeting of sperm and ovum. Intra Uterine Devices (IUDs) increase the phagocytosis of sperms within the uterus. Oral contraceptives inhibit ovulation and implantation, and also alter the quality of cervical mucus to prevent the entry of sperms. Surgical methods (sterilization) block gamete transport and thereby prevent conception. Therefore, the correct matching is A-IV, B-III, C-II, D-I. Answer: A-IV, B-III, C-II, D-I
