Explanation
Room I has 1 free berth, room II has 2 and room III has 3. Placing P and Q: both in II (1 way), both in III (1 way), one in II and one in III (2 ways), one in I and one in II (2 ways), one in I and one in III (2 ways) — room I can take at most one of them. The total is 8 ways. Hence option A is correct.
