Solution

The correct options are
B relaxes
C contracts
The walls of the chambers of the heart are made up of muscles. These muscles relax and contract rhythmically to bring about the pumping of blood. When the heart relaxes, it receives the blood and it contracts to pump the blood to all parts of the body.
