Eight students ($\mathrm{P, \:Q, \:R, \:S, \:T, \: U, \:V,}$ and $\mathrm{W}$) are playing musical chairs. The figure indicates their order of position at the start of the game. They play the game by moving forward in a circle in the clockwise direction.
After the $1^{\text {st }}$ round, $4^{\text {th }}$ student behind $\mathrm{P}$ leaves the game. After $2^{\text {nd }}$ round, $5^{\text {th }}$ student behind $\mathrm{Q}$ leaves the game. After $3^{\text {rd }}$ round, $3^{\text {rd }}$ student behind $\text{V}$ leaves the game. After $4^{\text {th }}$ round, $4^{\text {th }}$ student behind $\text{U}$ leaves the game. Who all are left in the game after the $4^{\text {th }}$ round?
Note: The figure shown is representative.

$\text{W} ; \text{R} ; \text{Q} ; \text{V}$
$\text{Q} ; \text{T} ; \text{V} ; \text{W}$
