BGrand father

CGrand Mother

DCannot be determined

Answer:

D. Cannot be determined

Read Explanation:

Let’s analyze carefully:

  • B is the daughter of A.

  • C is the husband of B.

  • D is the son of C.

Since D is the son of C and B, A is definitely the parent of B, so A is the grandparent of D.

However, the gender of A is not given.
So we cannot say whether A is the grandfather or grandmother of D.

Therefore, the precise relation cannot be determined.
