Checking each statement:

(A) K is the father-in-law of B.

K is the wife of S and mother of J. Since J is married to B, K is the mother-in-law of B, not father-in-law.

(A) is FALSE.

(B) J is the son-in-law of Q.

Q is the husband of C, and C is the mother of B, making Q the father of B. Since J is married to B, J is the son-in-law of Q.

(B) is TRUE.

(C) S is the father of B.

S is the father of J, not B. S is the father-in-law of B through J's marriage.

(C) is FALSE.

This is directly stated in the expression B + C.

(D) is TRUE.
