AIIMS 2018 Physics Equations of Motion Assertion Reason Question

Option A is correct because the assertion regarding the distances traveled in the first 2 seconds (x = 2a) and the first 4 seconds (y = 8a) is true, as derived from the equations of motion under constant acceleration. The reasoning that the distance traveled in the next 2 seconds (z = 6a) is indeed 3 times the distance of the first 2 seconds (3x) is also correct, but it does not provide a direct explanation for the assertion itself. Other options are incorrect because they either misinterpret the relationship between assertion and reason or incorrectly classify the truth values of the statements.
