Final answer:
The common tasks of replacing belts, hoses, water pumps, and thermostats are usually performed at an Automotive service center. This center handles vehicle maintenance, similar to an assembly line in a car factory.
Step-by-step explanation:
The work described in the question typically takes place at a D) Automotive service center. In such a center, technicians perform maintenance and repair tasks on various parts of a vehicle. Replacing automotive parts like belts, hoses, water pumps, and thermostats are common jobs performed here. These components are crucial for the proper functioning of a car's engine and cooling system. Just like in a factory where a car is assembled systematically, from the body to the wheels and steering wheel, an automotive service center systematically replaces worn or damaged parts to ensure the vehicle runs smoothly.
