Solution
The correct option is B Atria
The human heart has four chambers.The two upper thin walled chambers of the heart are called auricle or atria (singular: atrium) and two lower thick walled chambers are called ventricles. The chambers are separated by partition called septum. The septum between auricles and ventricles prevents the mixing of oxygenated and deoxygenated blood.
