Explanation:

Question 1

In a laboratory, safety goggles protect the eyes from chemicals, glass shards, or other hazards. Sunglasses are for sun protection, no equipment is unsafe, and a helmet is for head protection in other contexts (like construction), not labs.

Broken glass is sharp and should go in a designated glass container to prevent injuries and proper disposal. Regular trash, desk drawers, or sinks are unsafe or improper for broken glass.

Electrical equipment and water (from wet hands) are dangerous. Drying hands removes moisture to avoid electric shock. Washing hands is good hygiene but not specific to electrical safety, wetting hands is unsafe, and gloves aren't necessary here for this step.

Answer:

b) Safety goggles
