Which equipment can be used with nuclear weapons?

The correct option emphasizes that only equipment specifically included in the Master Nuclear Certification List (MNCL) can be used with nuclear weapons. This list is essential because it outlines the criteria and specifications that equipment must meet to ensure the proper handling, safety, and security of nuclear weapons. The MNCL is a critical safeguard against the misuse or accidental deployment of nuclear arms, ensuring that all associated equipment undergoes rigorous testing and evaluation.

Military-grade equipment, while potentially useful, does not automatically qualify for nuclear weapon use unless it is specifically certified in the MNCL. Similarly, commercial aviation devices and unmanned vehicles may have applications in various military operations, but they lack the necessary certification for direct use with nuclear weapons, which ensures a higher standard of safety and effectiveness in nuclear operations.
