I gave my students this multiple choice question: To safely conduct an experiment using chemicals, what should students always do?

Only one answer is correct among these 4 choices:
- Work in large groups.
- Wear safety goggles.
- Wear short sleeves.
- Keep a window open.

Could you tell me which one is correct?

Wear safety goggles.
