Q.

Match List I with List II related to embryonic development at various months of pregnancy:

List-IList-II
A.The foetus movement starts and hair appears on the head(I)24 weeks of pregnancy
B.The foetus develops limbs and digits(II)20 weeks of pregnancy
C.The foetus develops external genital organs(III)8 weeks of pregnancy
D.The foetus body is covered with fine hair; eyelids separate and eyelashes are formed(IV)12 weeks of pregnancy

Choose the correct answer from the options given below:

  1. A

    A-IV, B-II, C-III, D-I

  2. B

    A-II, B-III, C-IV, D-I

  3. C

    A-III, B-II, C-IV, D-I

  4. D

    A-II, B-IV, C-III, D-I

Solution

By 8 weeks (end of 2nd month) the foetus develops limbs and digits.

By 12 weeks (end of first trimester) most major organ systems and the external genital organs are well developed.

By 20 weeks (5th month) foetal movements are first felt and hair appears on the head.

By 24 weeks (end of second trimester) the body is covered with fine hair, eyelids separate and eyelashes are formed.

So A-II (20 weeks), B-III (8 weeks), C-IV (12 weeks), D-I (24 weeks).
