Final answer:
A Safety Committee is most effective when composed of a mixture of employees at all levels to include practical insights and policy-making abilities. Option D is correct.
Step-by-step explanation:
The most effective composition for a Safety Committee within a hotel is a mixture of employees at all levels. This ensures that the committee is well-rounded, with line staff providing practical insights based on their daily experiences on the job, and managers and executives offering the ability to make policy decisions and address crises with a macro-level view.
The diversity within the committee allows for better risk assessment, crisis management, and the development of safety protocols that are practical, enforceable, and supported throughout the organization.
