b and c are siblings. m has two children and he is son of e, who is father-in-law of h. h has only one son. c is not granddaughter of e. how is h related to m?

Let's analyze the relationships step-by-step based on the information provided:

Given Information:

1. b and c are siblings.
2. m has two children.
3. m is the son of e.
4. e is the father-in-law of h.
5. h has only one son.
6. c is not the granddaughter of e.

Step-by-step Reasoning:

• m is the son of e.
  So, e is the father of m.

• e is the father-in-law of h.
  This means h is married to e's child. Since m is e's son, h must be married to m's sibling (because h is the son-in-law or daughter-in-law of e).

• b and c are siblings.
  Since m has two children and b and c are siblings, it is logical that b and c are m's children.

• c is not the granddaughter of e.
  Since c is not the granddaughter of e, c cannot be a female child of m (because m is e's son, so m's children would be grandchildren of e). Therefore, c must be a male child (grandson) or the gender is not relevant here, but the key point is c is not a granddaughter, so c is likely a grandson or son.

• h has only one son.
  Since h is married to one of e's children (other than m), and h has only one son, this son could be b or c.

Conclusion:

• Since e is the father-in-law of h, h is married to m's sibling (either b or c).
• m and h are brothers-in-law (since h is married to m's sibling).

Final answer:

h is the brother-in-law of m.
