Usage of 哪些
'哪些' is a common interrogative pronoun used to ask about a selection or subset from a known group. It literally means 'which ones' or 'which of them.' It is often used when the speaker expects multiple items or options as an answer.
Common contexts
- Asking about preferences or choices among several items: 你喜欢哪些水果？
- Inquiring about a subset within a group: 这些书中哪些是你读过的？
- Planning or decision-making questions: 你打算参加哪些活动？
Collocations and patterns

- 这些 + noun + 中哪些: to ask which among these

Notes
'哪些' always refers to plural or multiple items, unlike '哪个' which refers to a single item. It is polite and neutral, suitable for both formal and informal contexts. Avoid confusing it with '什么' which asks 'what' in a more general sense without implying a selection from a known set.
