It must be safe, visible, simple and easily understood describes a:

• A. A safety briefing
• B. A lecture
• C. A workshop
• D. A demonstration

Answer: (D)

Describing something as safe, visible, simple, and easily understood fits a demonstration because it focuses on showing how to do a task in a clear, observable way. By watching a live, step-by-step performance, learners can see exactly what to do, in what order, and what safety precautions to follow, making the technique easy to understand and replicate. A safety briefing is mainly spoken information, a lecture is primarily verbal, and a workshop is more about participants practicing themselves, which can be less about a single clear visual demonstration of the correct steps. In fire safety education, a demonstration might show how to use a fire extinguisher or how to conduct a safe evacuation, with simple, watchable actions that reinforce proper technique.
