Answer:

The answer is A. The Muffler

Step-by-step explanation:

The first muffler for cars was designed in 1897.

The function of the car muffler is to slow down the speed of movement of the exhaust gases, which helps to smooth the movements of the engine, reduce the temperature of the gases and reduce the emissions of substances that are harmful to the environment.
