AIIMS 2018 Zoology Blood Groups Assertion Reason Question

Option B is correct because both the assertion and reason are true: A and B antigens are indeed present on red blood cells (RBCs) of individuals with the AB blood group. However, the reason provided does not correctly explain the assertion, as the presence of A and B antigens is characteristic of the AB blood group, but does not solely define it. Option A is incorrect because the reason does not adequately explain the assertion. Option C is incorrect because both statements are true, and option D is incorrect as both statements are factual. Understanding blood group antigens is crucial for blood transfusions and compatibility.
