Formula to find the average velocity of a body is given by:
$v_{av}=\frac{(u + v)}{2}$
$s_n =u + \frac{a}{2}(2n-1)$
$s=ut+\frac{1}{2}at^{2}$
$v=u+at$

Academic Physics NCERT Class 9

If the initial velocity of a moving body is $u$ and the final velocity is $v$,

Then, average velocity $v_{av}=\frac{u+v}{2}$

Therefore, option a). is correct.
