No-Lone Zones contain which of the following?

No-Lone Zones are specific areas where the presence of nuclear weapons is controlled to ensure safety and security measures are upheld. Within these zones, strict protocols are established to prevent individuals from being alone in locations where nuclear weapons are stored or handled. This is primarily for safety reasons, as it helps in managing the risks associated with these sensitive materials.

The correct option reflects that nuclear weapons are indeed found within No-Lone Zones, which is the defining characteristic of these areas. The management of nuclear weapons includes ensuring that personnel are always accompanied to promote accountability and reduce the chance of accidents or unauthorized access. Other materials such as non-nuclear munitions, classified materials, and explosive devices, while they may have their own secure areas and policies, are not the primary focus of No-Lone Zones specifically designated for nuclear weapons.
