Both Assertion and Reason are true and Reason is the correct explanation of Assertion
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false
Both Assertion and Reason are false
Correct Answer
Detailed Explanation
Option C is correct because the assertion that the technique shown in the figure is frequently used in prenatal disease treatment is true, as techniques like amniocentesis or chorionic villus sampling (CVS) are employed to diagnose genetic disorders before birth. However, the reason is false; these techniques can indeed be used for sex determination of the fetus by analyzing the chromosomal makeup (XX or XY) obtained from the amniotic fluid or placental tissue.
Option A is incorrect because, while both statements are true, the reason does not explain the assertion. Option B is incorrect because the reason is false, and thus cannot be a valid explanation. Option D is incorrect as the assertion is true.
