III. Q is not taller than T and R.

Options

A. Only I and II
B. Only II and III
C. Only I and III
D. All I, II and III

Answer

A

Explanation

From I, we have: `P gt D,P gt N, Tgt P i.e. T gt P gt D gt N" or "Tgt P gt N gt D`.....(i)
From II, we have: `R gt Q,T gt R i.e. T gt R gt Q` ...(ii)
From III, we have: `Tgt Q,R gt Q`...(iii)
Clearly, from (i) and (ii), we conclude that T is taller than each one of P, N, D, R and Q. So, Tis the tallest.
