Solution

$\begin{array}{l}
\,\,\,\,\,For\,a\,body\,thrown\,vertically\,upwards\,acceleration\,\\
remains\,{\rm{constant}}\,(a =  – g)\,and\,velocity\,at\,anytime\,t\,is\,\\
given\,by\,V = u – gt\\
During\,rise\,velocity\,decreases\,linearly\,and\,during\,fall\,\\
velocity\,increases\,linearly\,and\,direction\,is\,opposite\,to\\
each\,\,other.\\
Hence\,graph\,\left( C \right)\,correctly\,depicts\,velocity\,versus\,time.
\end{array}$
