Answer 1

The correct option is C

If the data either in statement I alone or in statement II alone are sufficient to answer the question

From I, we conclude that the man is the only son of Sonia's grandfather i.e. he is Sonia's father or Sonia is the man's daughter. From II, we conclude that the man's father is Sonia's grandfather. Since the man has no brothers or sisters, so he is Sonia's father or Sonia is the man's daughter.
