Q.99. Match the following components listed in Column I with their respective organs in Column II
Column I
P. Endolymph
Q. Vitreous humour
R. Vas deferens
S. Corpus luteum
Column II
(i) Testes
(ii) Ear
(iii) Ovary
(iv) Eye
(A) P-(ii), Q-(iv), R-(i), S-(iii)
(B) P-(ii), Q-(i), R-(iv), S-(iii)
(C) P-(iii), Q-(iv), R-(i), S-(ii)
(D) P-(iii), Q-(iv), R-(ii), S-(i)
The correct answer to this NEET-style matching question is option (A): P-(ii), Q-(iv), R-(i), S-(iii). This pairs each fluid or structure accurately with its primary organ based on human anatomy.
Component Locations
Endolymph fills the membranous labyrinth of the inner ear, aiding balance and hearing. Vitreous humour is a gel-like substance occupying the posterior chamber of the eye, maintaining shape and supporting the retina. Vas deferens serves as a duct in the male reproductive system within the testes region, transporting sperm. Corpus luteum forms in the ovary post-ovulation, secreting progesterone.
Option Breakdown
-
Option (A) correctly matches P-endolymph to ear (ii), Q-vitreous humour to eye (iv), R-vas deferens to testes (i), and S-corpus luteum to ovary (iii).
-
Option (B) errs by linking vitreous humour to testes (i); it belongs in the eye, not male gonads.
-
Option (C) incorrectly assigns endolymph to ovary (iii) and vas deferens to ear (ii), confusing sensory and reproductive anatomy.
-
Option (D) wrongly pairs endolymph with ovary (iii) and corpus luteum with testes (i), mixing female and male structures.
Exam Preparation Tips
Master these pairings through diagrams of ear, eye, and reproductive systems for quick recall in MCQs. Relate endolymph to cochlear function, vitreous humour to vision clarity, vas deferens to sperm pathway, and corpus luteum to menstrual cycle regulation. Practice similar match-the-column questions from NCERT biology chapters on human physiology.
