The following equation describe the motion of object where $x$ is displacement, $v,v_0$ are velocities, $m$ mass $V=Axe^{Bm}-\large\frac{c^2}{v^0}$. What must be the unit of $A$ and $B$?

Question

$$\begin{array}{1 1}(a)\;A\;is\;\frac{1}{second}\;B\;is \;meter \\(b)\;A\;is\;\frac{1}{second}\;B\;is \;\frac{1}{kilogram} \\ (c)\;A\;is\;second\;B\;is \;meter \\ (d)\;A\;is\;second \;B\;is \frac{1}{kilogram}\end{array}$$
