DIf P is the daughter of B, then A and P are sisters ✓ Correct

Correct answer: (D) If P is the daughter of B, then A and P are sisters

Explanation

The true statement is: if P is the daughter of B, then A and P are sisters.

Given A is B's daughter, B is C's son, C is D's father.

So B and D are both children of C, and A is C's grandchild.

If P is also a daughter of B, then A and P share the same parent B.

Two daughters of the same parent are sisters.

Hence A and P are sisters.
