  • BBoth statements together are needed (neither alone is sufficient)
  • CStatement II alone is sufficient but Statement I alone is not
  • DStatement I alone is sufficient but Statement II alone is not

Step-by-Step Solution

From I, P (a son) shares Q's mother, so P is Q's brother. From II, Q (a daughter) shares P's father, so Q is P's sister, i.e. P is Q's brother. Each statement alone fixes the relation, so either one is sufficient.
Answer: A) Either statement alone is sufficient
