N is father of D. D is sister of K. K is son of T. J is son of K. M is the brother of J. C is the wife of K. B is daughter of D. How N is related to B.

To determine how N is related to B, let's identify the relationships from the information provided:

1. N is the father of D: This means D is a child of N.

2. D is the sister of K: Since D and K are siblings, they share the same parents, specifically N (father) and presumably another parent.

3. K is the son of T: This indicates that T is K's other parent and thus a parent of D as well.

4. J is the son of K: J is K's child, making J the grandson of N and T.

5. M is the brother of J: M, being the brother of J, is also a grandson of N and T.

6. C is the wife of K: C is K's spouse, which means she is also the mother of J and M.

7. B is the daughter of D: Therefore, D is B's mother, making B the granddaughter of N.

Now, putting these relationships together:

• N is the father of D.
• D is the mother of B.

Therefore, N is the grandfather of B.

Final Answer
