Solution

The correct option is A $v_{A} + v_{B}$
As seen from the image, object $B$ and image of $A$ will be on the same line, thus for relative speed between them
$V_{B A i} = V_{B} + V_{A}$

Q. When two bodies are moving in opposite directions along a straight path then the relative velocity of each body is greater than the absolute velocity of either body.
let the velocity of A and B moving in opposite directions be Va and Vb respectively.
Va=+V , Vb=-V
Velocity of B with respect to A
Vb - Va = -V-V= -2V which is not greater than the absolute velocity of B i.e, V
