Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The first movements of the foetus and the appearance of hair on the head are typically observed by the end of 24 weeks of pregnancy. Reason (R): By the end of the second trimester, the body is covered with fine hair, eyelids separate, and eyelashes are formed. In the light of the above statements,
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A).
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- C(A) is correct but (R) is not correct.
- D(A) is not correct but (R) is correct.
Correct answer
D. (A) is not correct but (R) is correct.
Step-by-step solution
Assertion (A) is incorrect because the first movements of the foetus and the appearance of hair on the head are observed during the fifth month (around 20 weeks) of pregnancy, not by the end of 24 weeks. Reason (R) is correct because by the end of about 24 weeks (which marks the end of the second trimester), the body is covered with fine hair, eyelids separate, and eyelashes are formed. Therefore, (A) is not correct but (R) is correct. Answer: (A) is not correct but (R) is correct.
