Which safety guideline mentions daylight and reflective clothes?

• A. Carry out in groups
• B. Carry out coursework in daylight and wear reflective clothes
• C. Always tell an adult
• D. Check study area

Answer: (B)

The main idea here is visibility and safety when working outdoors. Being clearly seen and able to spot hazards reduces the risk of accidents during fieldwork. Daylight helps you see hazards better, and wearing reflective clothes makes you more visible to others, especially if light fades or you’re near traffic or in shady areas. A guideline that says to carry out coursework in daylight and wear reflective clothes directly ties safety to how visible you are while outside. The other options mention general safety practices like working in groups, telling an adult, or checking the area, but they don’t specifically address daylight and reflective visibility in the same way.
