Second option: J is the wife of the son of M – From the above family tree, it's clear that J is the daughter of M and H is the son-in-law of M. Therefore, this option is incorrect.
Third option: H is the husband of the sister of L – From the above family tree, it's clear that J is the sister of L, and H is J's husband. So, H is the husband of the sister of L . Therefore, this option is correct.
