Let us define a motion as $A$ when velocity is positive and increasing,$A^{-1}$ when velocity is negative and increasing,$R$ when velocity is positive and decreasing,and $R^{-1}$ when velocity is negative and decreasing. Now,match the following two columns for the given $s-t$ graph.

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

• A
  $(A \rightarrow r, B \rightarrow s, C \rightarrow p, D \rightarrow q)$
• B
  $(A \rightarrow p, B \rightarrow s, C \rightarrow r, D \rightarrow q)$
• C
  $(A \rightarrow r, B \rightarrow p, C \rightarrow s, D \rightarrow q)$
• D
  $(A \rightarrow q, B \rightarrow s, C \rightarrow p, D \rightarrow r)$
