III. Q is not taller than T and R.

Options

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

Answer

A

Explanation

From statement I:
P `gt` D, P`gt` N, T`gt` P. So, T`gt` P`gt` D`gt` N or T `gt` P`gt` N`gt` D.
But there is no information regarding Q and R. So, statement I alone is not sufficient.
From statement II :
R`gt` Q, T`gt` R So, T`gt` R`gt` Q
But there is no information regarding P, N and D. So, statement II alone is not sufficient.
From statement III :
T`gt` Q, R`gt` Q.
But there is no information regarding P, N and D. So, statement III alone is not sufficient.
From (i) & (ii), we get
T is the tallest.
Therefore only statements I and II together are necessary to answer the given question.
