For the velocity-time graph shown in the figure, in a time interval from $t=0$ to $t=6\,s$, match the following columns.

Colum $I$	Colum $II$
$(A)$ Change in velocity	$(p)$ $-5 / 3\,Sl$ unit
$(B)$ Average acceleration	$(q)$ $-20\,SI$ unit
$(C)$ Total displacement	$(r)$ $-10\,SI$ unit
$(D)$ Acceleration at $t=3\,s$	$(s)$ $-5\,SI$ unit

• A

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

• B

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

• C

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

• D

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