Let us call a motion, A when velocity is positive and increasing, ${\mathrm{A}}^{-1}$ , when velocity is negative and increasing. R when velocity is positive and decreasing and ${\mathrm{R}}^{-1}$ when velocity is negative and decreasing. Now, match the following two columns for the given s-t graph and mark the correct option from the codes given below.

Column I	Column II
(A)     M	(p)   ${\mathrm{A}}^{-1}$
(B)     N	(q)   ${\mathrm{R}}^{-1}$
(C)     P	(r)    A
(D)     Q	(s)    R
