$y=\large\frac{x}{2}$ =>  the particle is moving in a straight line passing through orgin.
since $y=\large\frac{x}{2}$ we have
$v_y=\large\frac{v_x}{2}$$=>v_y$=2- t
=>$a_y=-1$ is also negative
$v_x\;and \;v_y$ are positive
$a_x \; and\;a_y$ are negative
=>motion is first retarded then accelerated
Hence c is the correct answer.
