The answer is<u> "a. joint operations center".</u>
In light of noteworthy dangers or incidents including Federal violations under the criminal purview of the United States, the FBI may set up a JOC, a local multi jurisdictional interagency investigative, knowledge, and tasks focus to lead and arrange the law requirement reaction, investigative tasks, and related insight exercises.
The JOC is driven by a FBI On-Scene Commander and is upheld by a Federal, state, nearby, regional, and innate summon gathering and an outcome administration gathering, as fitting.
The JOC is the place from which the FBI leads and organizes the law requirement operational reaction, on-scene law implementation, and related investigative and insight exercises.
