The correct answer is C. Son-in-law.
The woman’s mother-in-law is the sister of the man in the photograph. This means that the man in the photograph is the woman’s husband’s uncle. The woman’s husband is therefore the son of the man in the photograph.
Here is a diagram to illustrate the relationship:
[Diagram of a family tree with the woman, her husband, the man in the photograph, and their respective relatives]
The woman is represented by the blue circle, her husband is represented by the red circle, the man in the photograph is represented by the green circle, and their respective relatives are represented by the other circles.
The woman’s mother-in-law is the sister of the man in the photograph. This means that the man in the photograph is the woman’s husband’s uncle. The woman’s husband is therefore the son of the man in the photograph.
The woman’s husband is the son of the man in the photograph. This makes the man in the photograph the woman’s husband’s father. The woman’s husband is therefore the man in the photograph’s son-in-law.
The other options are incorrect because they do not accurately reflect the relationship between the woman, her husband, and the man in the photograph.
- Option A is incorrect because the woman’s husband is not the grandson of the man in the photograph. The man in the photograph is the woman’s husband’s father, not his grandfather.
- Option B is incorrect because the woman’s husband is not the son of the man in the photograph. The man in the photograph is the woman’s husband’s father, not his son.
- Option D is incorrect because the woman’s husband is not the nephew of the man in the photograph. The man in the photograph is the woman’s husband’s father, not his nephew.
- Option E is incorrect because the woman’s husband is related to the man in the photograph. The man in the photograph is the woman’s husband’s father.
