Which of the following is a level of MOPP?

MOPP, or Mission Oriented Protective Posture, is a system used by military and emergency response personnel to determine the level of protective gear required in response to chemical, biological, radiological, and nuclear (CBRN) threats. The levels range from MOPP 0, which indicates no protective gear is needed, to MOPP 4, where full protective gear is worn.

MOPP 0 is the baseline level that represents a state of preparedness without any protective equipment. This means that personnel are not at immediate risk from a CBRN threat and can operate normally while remaining vigilant.

The other options—MOPP 5, MOPP 6, and MOPP 7—do not exist within the standardized MOPP levels, which officially range only from MOPP 0 to MOPP 4. Therefore, only MOPP 0 is correct within the context of this question as a recognized level of MOPP.
