The correct answer is C. Locomotive.
A locomotive is a type of railway vehicle that provides the motive power for a train. It is usually powered by a diesel engine, but can also be powered by an electric motor or steam engine. The locomotive is responsible for pulling the train along the track, and must be able to provide enough power to overcome the resistance of the train and the track. This requires a high starting torque, which is the torque that is required to start a rotating object from a standstill.
The other options are incorrect because they do not require a high starting torque. A lathe machine is a machine tool that is used to turn metal or other materials. It does not require a high starting torque because it is not required to move a large mass. A centrifugal pump is a type of pump that uses centrifugal force to move fluids. It does not require a high starting torque because the fluid is already moving when it enters the pump. An air blower is a device that is used to move air. It does not require a high starting torque because air is a very light gas.
