Answer: D — Neither I nor II

Given: $P=4$, $R=1$, $Q

e 5$,$S

e 2$,$T

e 3$. The remaining ranks${2,3,5}$are distributed among$Q$,$S$,$T$.

Statement I: If $S=3$, then $T=2$.

If $S=3$, then $Q$ and $T$ take $\{2,5\}$. Since $Q

e 5$, we must have$Q=2$, which forces$T=5$. So$T=5$, not$2$. Statement I is incorrect.

Statement II: If $Q=3$, then $T=5$.

If $Q=3$, then $S$ and $T$ take $\{2,5\}$. Since $S

e 2$, we must have$S=5$, which forces$T=2$. So$T=2$, not$5$. **Statement II is incorrect.
