T-S means T is the wife of S, similarly, B-M means B is the wife of M.

S*B means S is the son of B.

clearly, T, B is female, and S, M is male here. 

From the above figure:

  1. $B$ is the mother of $S$: True
  2. $M $is the husband of $B$: True
  3. $S$ is the daughter of $B$: false because $S$ is male, $S$ is the son of $B$.
  4. $T$ is wife of $S$: True.

Option C is false here.
