Question

Match the months listed in Column-I with the organogenesis of foetus in Column-II.

Column-I		Column-II
(i)	First month	(a)	Separation of eye lids
(ii)	Second month	(b)	Hairs on head
(iii)	Fifth month	(c)	Heart
(iv)	Six month	(d)	Limbs & digits

Choose the correct options :

• A. (i)-(c), (ii)-(d),(iii)-(a),(iv)-(b)
• B. (i)-(b), (ii)-(c),(iii)-(d),(iv)-(a)
• C. (i)-(d), (ii)-(b),(iii)-(c),(iv)-(a)
• D. (i)-(c), (ii)-(d),(iii)-(b),(iv)-(a)

Answer 1

The Correct Option is D

First month (i): The heart (c) begins to form and starts beating by the end of the first month (around day 21-23). This is one of the first organs to develop.

Second month (ii): Basic structures of all major organs develop, including limbs and digits (d). By the end of the second month, the embryo has distinct fingers and toes.

Fifth month (iii): Hair on head (b) (lanugo) appears, along with other features like quickening (mother feels movement).

Sixth month (iv): Separation of eyelids (a) occurs, and the eyes may begin to open. The fetus also develops more fat and more defined features.

The correct matching is therefore: (i)-(c), (ii)-(d), (iii)-(b), (iv)-(a)

Thus, the correct option is (D) (c) (d) (b) (a).
