Answer:
C. Modular Organization
Explanation:
Modular Organization is one of the key characteristics of the National Incident Management System (NIMS). Both emergency operations centers and Incident Command Systems are build based on the modular structure. They organize incidents according to their scale, hazardous environment and level of complexity.
Modular organisation also indicates that people leading specific units are in charge of functions of the lower-ranking positions, which lack in staffing.
