D) 5 pm

E) None of these

Answer:

Option C

Explanation:

We first form the sequence of visit using (iv), (v) and (vi).

From (iv), we know that Q visits first and U visits last.

From (v), we know that W visits first after break and is followed by R.

From (vi), we know that P visits after the break.

Thus, the sequence of visit after break becomes W R, P, U. Also S has the same position in the morning session as P in afternoon session. So, the sequence of visit before break is Q, T/V, S, V/T.

The time of visit of W is 2 p.m. to B p.m., that of doctor R is 3 p.m. to 4 p.m. so, the visit of doctor R is over at 4 p.m. Hence, the answer is (c).
