Relationships:

- 3 married couples (husbands and wives)
- 2 pairs of siblings

Given information:

- D's father-in-law is E
- F's daughter-in-law's brother is G
- Members in each pair of siblings are of different genders
- H likes B, the daughter of C and E
- A is B's sister-in-law
- Two of the three married couples have two children each

To find: How is D related to B?

Solution:

First, let's identify the family tree diagram for the given information:

+---A (wife) -+- B (sister-in-law)
| |
+---C (husband) +---E (husband)
| | | |
| +---H | +---D (husband)
| | |
+---F (husband) +---G (brother) +---(wife)

From the diagram, we can infer the following:

- A is married to one of B's siblings. Since it is not mentioned whether A is a male or female, we don't know whether A is B's brother-in-law or sister-in-law.
- C and E are married to each other, and H likes B, who is their daughter.
- D is married to one of E's children, but we don't know whether it is a son or daughter.
- F is married to one of G's siblings, who is also married to one of D's siblings.

Now, let's use the given information to find the relationship between D and B:

- D's father-in-law is E, which means D is married to one of E's children. Since we don't know whether it is a son or daughter, we can't determine the exact relationship yet.
- F's daughter-in-law's brother is G, which means F is married to one of G's siblings, who is also married to one of D's siblings. This implies that F and D are brothers-in-law.
- A is B's sister-in-law, which means B is married to one of A's siblings. However, we don't know whether it is a brother or sister of A.
- Two of the three married couples have two children each, which means that one of the married couples has only one child.

Now, let's combine all the information:

- D is married to one of E's children, and F is D's brother-in-law.
- A is married to one of B's siblings, and one of the married couples has only one child.
- H likes B, who is C and E's daughter.

From the above information, we can conclude that:

- D is E's son, and he is married to B, who is A's sister.
- A is married to B's brother, who is also E's son.
- F is married to G's sister, who is also D's sister.

Therefore, D is related to B as her husband, which is option (c).
