What is the main goal of the Nuclear Personnel Reliability Program?

The main goal of the Nuclear Personnel Reliability Program (PRP) is to ensure the emotional and professional reliability of personnel who have access to nuclear weapons and associated systems. This program is designed to assess and maintain the reliability of these individuals to prevent unauthorized or inappropriate use of nuclear weapons. It emphasizes mental and emotional fitness, as well as a commitment to integrity and accountability among personnel. This holistic approach seeks to safeguard national security by ensuring that those who handle sensitive and critical nuclear responsibilities are trustworthy and capable of making sound decisions under pressure.

The other options, while relating to security or personnel management in some capacity, do not encapsulate the primary focus of the PRP. The program does not primarily function to authorize access to command systems, classify personnel into sensitivity levels, or monitor financial accountability of contracts, making option B the most relevant and accurate representation of the program's goals.
