Explanation:

1.

In a laboratory, safety goggles protect eyes from hazards. Sunglasses aren't for lab safety, no equipment is unsafe, and a helmet is unnecessary for general lab apparatus handling.

Broken glass must go in a designated glass container to prevent injuries and proper disposal. Regular trash, desk drawers, or sinks are unsafe/improper.

Wet hands with electricity are dangerous (risk of shock). Dry hands are safe; washing or wearing gloves isn't the pre - use step for electrical equipment here.

Answer:

b) Safety goggles
