Solution & Explanation
Answer: (D) (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv) Solution: Vaults are barriers that block entry of sperms through the cervix (i); IUDs increase phagocytosis of sperms within the uterus (iii); vasectomy removes a part of the vas deferens (ii); tubectomy removes a part of the fallopian tube (iv). Only option (D) pairs every method with its correct mechanism. NCERT Reference: Reproductive Health, p.44 — "They prevent conception by blocking the entry of sperms through the cervix."
