The correct choice highlights that operations which are hazardous to nonparticipating aircraft are prohibited in classified restricted areas. Restricted areas are established for safety and security reasons, often due to military activities, national defense, or other sensitive operations. These areas are marked as off-limits to civilian aircraft unless specific clearance is granted.

The prohibition of hazardous operations is crucial because the primary objective of restricted areas is to ensure the safety of all air traffic. If a civilian or nonparticipating aircraft were to enter these areas during critical operations, it could potentially lead to dangerous situations, including collisions or interference with military exercises. Thus, for the safety of both the military activities taking place and civilian air traffic, such operations are strictly regulated.

In contrast, the other options do not fully capture the safety single-mindedness of restricted areas. While all flights without ATC clearance may generally be discouraged, certain operations could still be permitted under specific conditions if clearance is obtained. Visual flight rules can also apply in some restricted areas if the appropriate permissions are received. Finally, while commercial air transport generally tends to follow stricter regulations, there are instances where commercial flights may coordinate with ATC for approved access to these airspaces. Therefore, the primary concern in restricted areas revolves around the safety implications
