The correct answer focuses on the essential safety procedures that a Train Operator (T/O) must conduct to ensure the train is operating safely and efficiently. The T/O check includes verifying that the brakes are functioning properly and ensuring that all tags are in place and indicate that systems are operational. This inspection is crucial for maintaining safety standards on the transit system, as functioning brakes directly impact the ability of the train to stop safely during operation.

Other options, while relevant to train operations, do not reflect the primary responsibilities during a T/O check. Checking the body condition of passengers pertains more to passenger safety and comfort than operational checks. Monitoring temperature and air conditioning is important for passenger comfort but does not take precedence over safety checks like brakes. Lastly, fuel levels and oil pressure relate to the maintenance of the train's mechanical systems but do not fall under the immediate scope of what a T/O would check inside passenger cars during routine inspections.
