Explanation:

- Winning from lottery: Lottery winnings aren't included in national income. They are considered a transfer payment, not a part of the production of goods and services.

- Milk purchase by a dairy shop: This transaction counts as an intermediate purchase. It doesn't directly add to the national income, which includes final goods and services.

- National debt interest: Interest paid on national debt is a transfer payment. It doesn't add to the current production of goods and services, so it's not included in national income.

- None of these: This option indicates that none of the above transactions directly contribute to the national income.
