B. functions and positions remain the same throughout the incident regardless of expansion.
C. all functions of the Command and General Staff must be filled.
D. only the functions and positions necessary are filled.

Answer: D

Only the functions and positions necessary are filled.

Explanation

The systems of ICS adhere to the incident action strategy, command unity, individual accountability, and source tracking.
ICS works flexibly and can contract and extend according to the circumstances.
The vacant posts filling depends on the incident.

So, when an incident expands, only the functions and positions necessary are filled.
