Explanation:

- Let's break down the expression: ‘D × O ÷ E + Y’.

- ‘D × O’ means D is the sister of O.

- ‘O ÷ E’ means O is the son of E.

- Combining the two, D is the sister of O, who is the son of E. Therefore, D is the daughter of E.

- ‘E + Y’ means E is the husband of Y.

- Therefore, D is the daughter of E and Y.

- Now, let's determine D's relation to Y. Since E and Y are a married couple and D is their daughter:

- D is the Daughter of Y.

- Evaluate the options:

- Option 1: Sister

- Option 2: Daughter-in-law

- Option 3: Daughter
