Explanation:

- Taran is referring to a picture and describing a woman's relationship to her husband.

- The woman in question is the "mother of the father-in-law of my husband."

- Taran's "husband" implies her spouse.

- Her husband's "father-in-law" is Taran's father.

- The "mother" of Taran's father is Taran's grandmother.

- Thus, the woman in the picture is Taran's grandmother.

- Option 1: Mother - This would mean Taran is the daughter, but the description specifies a generational step above.

- Option 2: Granddaughter - Taran, being the granddaughter of the woman in the picture, fits this relationship.

- Option 3: Sister - This would not fit as the picture refers to an older generational relationship.

- Option 4: Daughter - Implies mother-child but here it's grandmother-grandchild.

- Correct Answer: Option 2: Granddaughter
