In a two block system shown in the figure, the two blocks have velocities in same horizontal direction. Mark the CORRECT statement about 'the velocity of the centre of mass' of the system with respect to a stationary frame:

$\begin{matrix} {\to V}_{c m} is a function of time and will become \to 0 at some instant(s) \end{matrix}$
${\to V}_{c m}$ is non zero all the times
${\to V}_{c m} is \to 0$ at all times
${\to V}_{c m} may be \to 0$ at some instant(s)
