Final answer:
The role of a trusted agent, responsible for maintaining the confidentiality and integrity of an exercise, is a collective responsibility of all members of the exercise planning team.
Step-by-step explanation:
In the context of exercise planning, a trusted agent is an individual who upholds the integrity of the exercise by ensuring confidentiality is preserved throughout the process. The trusted agent is responsible for handling sensitive information and ensuring that exercise materials that are not intended for broader distribution are kept secure. The question at hand concerns which member of the exercise planning team serves in this critical role.
The correct answer to the question is c. all members of the exercise planning team. The reasoning behind this answer is that maintaining the integrity and confidentiality of the exercise involves collective responsibility. Every member must adhere to the necessary protocols to ensure that sensitive information is not compromised, thus the role of the trusted agent does not fall solely on an individual such as the lead exercise planner, the subject matter expert (SME), or the safety officer; instead, it encompasses the responsibilities of the entire team.
