Answer: Technician A is correct.

Explanation:

Poor Wheel Bearings causes a car when driven to make noise when turning and it sounds like grinding. Bearings act like a cushion between an axle and the wheel. Due to the action of the bearings, they reduce to the barest minimum the friction between the two moving parts. That's why, a worn out wheel bearings leads to friction that causes the grinding sound when turning as the car bends.

In the case of the question the growling sounds are heard from the rear wheels, which increases the likelihood that faulty bearing is the rear ones.
