The heart functions in your body as a muscle that helps to pump oxygen around the body. Option A is correct.
The heart is a vital organ located in the chest cavity, slightly to the left of the center of your chest. The main function of the heart is to pump blood throughout the body, supplying oxygen and nutrients to all the cells and organs.
