A is the husband of B, C is the mother-in-law of B, D is the father of A, E is the mother of D, F is the mother of C and G. If H is the father of D, then what is the relation of H with E?

Let's break down the relationships step by step:A is the husband of B: A (Male) $\leftrightarrow$ B (Female).C is the mother-in-law of B: This means C is the mother of B's husband, A. So, C is the mother of A.D is the father of A: Since C is the mother of A and D is the father of A, C and D are married couple ($C\leftrightarrow D$).E is the mother of D.H is the father of D (given in the conditional part).Since E is the mother of D and H is the father of D, H and E must be husband and wife ($H\leftrightarrow E$).Thus, H is the husband of E.
