Explanation:

- Cooking for the family by a homemaker:

- This is a non-market activity. It's not included in national income as it doesn't involve a monetary transaction.

- Cleaning the bookshelf by a student:

- This task is a personal household activity. It lacks a market transaction or income element, so it's not part of national income.

- Helping the daughter with her homework by a teacher:

- This is a personal contribution without a paid exchange. Thus, it isn't accounted for in national income.

- All of the above:

- These activities do not include market value or paid contributions, so none are included in national income calculations.

All of the above is the correct answer.
