The correct answer is: A. DOM
The DOM (Director of Operations) is the most senior person in the control office. They are responsible for the overall safety and operation of the plant. In the event of a serious accident, the DOM will be the one in charge of the control office. They will make all the decisions about how to respond to the accident and will ensure that the plant is shut down safely.
The AOM (Assistant Operations Manager) is the second most senior person in the control office. They are responsible for the day-to-day operations of the plant. In the event of a serious accident, the AOM will assist the DOM in making decisions and will help to ensure that the plant is shut down safely.
The Sr. DOM (Senior Director of Operations) is a more experienced DOM. They may be called upon to assist the DOM in the event of a serious accident.
None of these is the correct answer.
