Solution

The correct option is A right auricle
A human heart consists of four chambers - two auricles and two ventricles. The human heart is also myogenic in nature. A heart which is self-excitable is called a myogenic heart.
In a myogenic heart, the heartbeat is controlled by a modified muscular tissue called sinoatrial node that initiates electrochemical impulse. The sinoatrial node is located in the right atrium. It is also called the pacemaker as it sets the pace at which the heart beats.

Bundle of His is situated in the interventricular septa, which is a partition present between the two ventricles.
