Given:

• ‘X @ Y’ means X is the husband of Y
• ‘X # Y’ means X is the father of Y

To Find:

• B%C means B is the daughter of C
• C#D means C is the father of D

Tree diagram of the family is given below

From the tree diagram we can clearly see that D's gender is not known so we can not determine how A is related to D. D can be Brother-in-law or Sister-in-law.
