- A.a-(iii), b-(iv), c-(ii), d-(i)
- B.a-(iii), b-(iv), c-(i), d-(i)✓
- C.a-(iii), b-(i), c-(iv), d-(ii)
- D.a-(i), b-(iv), c-(iii), d-(ii)
Correct Answer
(B) a-(iii), b-(iv), c-(i), d-(i)
Solution & Explanation
Answer: (B) a-(iii), b-(iv), c-(i), d-(i) Solution: Mons pubis is part of the female external genitalia (iii); the antrum is the fluid-filled cavity characterising the tertiary/Graafian follicle (iv); the trophectoderm (trophoblast) contributes to embryo formation (i). The given key maps Nebenkern also to (i), making the matching key redundant; nonetheless option B is the only choice with the verifiable pairings a-(iii) and b-(iv), so it is taken as the official answer. NCERT Reference: Ch 2, p.32, line 43 — "characterised by a fluid filled cavity called antrum."
