Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-III, B-IV, C-I, D-II
(A) Tubectomy — this matches (III) Surgical method of sterilisation in human female. A small part of each fallopian tube is removed or tied up.
(B) Copper ions — this matches (IV) Suppress motility of sperms. Copper-releasing IUDs such as CuT release Cu ions, which suppress sperm motility and their fertilising capacity.
(C) Cervical Cap — this matches (I) Barrier method. It covers the cervix and stops sperms from entering.
(D) Vasectomy — this matches (II) Surgical method of sterilisation in human male. A small part of each vas deferens is removed or tied up.
