Question

A particle moves along a straight line path. Its speed decreases continuously and after some time it comes to rest. The motion is with constant acceleration whose direction with respect to the direction of velocity is, positive throughout motion, negative throughout motion, first positive then negative, first negative then positive

MARKS App · Accepted Answer

As the speed decreases continuously therefore the motion is retarded and acceleration and velocity must be in opposite direction.
