Answer:
Both Technician A and Technician B are right
Explanation:
The Supplemental Restraint System (SRS) popularly known as "Air Bag" is basically an air-bag system. It works together with conventional 3-point seat belts and prevents impact of the driver's chest and face with the steering wheel in the event of an accident and it must be disabled before performing service on or around system components, steering column, instrument panel components, wiring and sensors.
This makes technician A correct.
The airbag connectors are bright yellow in order for them to be identified easily.
This makes technician B correct too.
