- Let's start with F being the sister-in-law of I and having two children. F is married to M, who is the brother-in-law of J's grandfather. Hence, M is J's grandfather.
- **N is the daughter of F**. N has an only son, and H is N's brother-in-law.
- **J is the son of K.** Since J doesn't have a sister, K must be either N or H.
- **From the given statement G belongs to the first generation,** and there are two married couples, G is the only possible parent of F or I.
- **L is G’s child,** and M is married to F. So, M is J's grandfather.
- Now, if G does not have a brother, then G is the parent of either F or I without a brother.

Connecting the relationship, finally, **I is the Paternal Aunt of the sister-in-law of H.**

Therefore, the correct answer is:

✅ **Option 4: Paternal aunt**
