A disc rolls on ground without slipping. Velocity of centre of mass is (\nu). There is a point $P$ on circumference of disc at angle ($\theta$). Suppose, $v_p$ is the speed of this point. Then, match the following columns
(

	Column I		Column II
(A)	If $\theta =$60^{}^{\circ}	(P)	v_P = $\sqrt{2}$v
(B)	If $\theta =$90^{}^{\circ}	(Q)	v_P = v
(C)	If $\theta =$120^{}^{\circ}	(R)	v_P = 2v
(D)	If $\theta =$180^{}^{\circ}	(S)	v_P = $\sqrt{3}$v
