easy

$Assertion$ : Velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to the time axis.
$Reason$ : In uniform motion of an object velocity increases as the square of time elapsed.

AIf both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

BIf both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

CIf the Assertion is correct but Reason is incorrect.

DIf both the Assertion and Reason are incorrect.

Solution

In uniform motion the object moves with uniform velocity, the magnitude of its velocity at different instance i.e., at $t = 0, t =1, sec, t = 2\,sec …..$ will always be constant. Thus velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to time axis.
