Solution

The correct option is B
Bicuspid valve

Heart has four chambers. The upper two chambers are called as auricles or atria and lower two chambers are called as ventricles. Between auricles and ventricles, there are valves present to prevent backflow of blood. Also, valves are located at the point of origin of major blood vessels.

Bicuspid valve guards the opening between the left auricle and left ventricle.
