What characterizes the qualitative standards used in the evaluation of nuclear weapon systems?

Qualitative standards for evaluating nuclear weapon systems emphasize ensuring safety against various threats and risks. This is essential in the context of nuclear weapons, as the consequences of failure or misuse can be catastrophic. By focusing on safety measures and robust assessments of potential threats, these standards help maintain operational integrity and public trust in nuclear capabilities.

The other choices do not capture the primary intention behind these qualitative standards. While the complexity of implementation and cost-effectiveness may be considerations in the broader evaluation process, they do not reflect the primary focus on safety inherent in these systems. Additionally, while training and support are important, they are not the central theme of qualitative standards when specifically dealing with the evaluations related to nuclear weapon systems.
