technician A

technician B

both technician A and B

neither tecnician B and B

The answer is both technician A and B

Explanation:

Possible indication of by the red brake lamp is faulty brake system, since when the brake pedal is pushed normally it is turned on. Hence this indicates a faulty brake system if it is turned on without pushing the brake pedal.

Also the brake light is turned on when ever there is shortage in brake fluid, this signals that there is a possible fault in the braking system.
