The correct option is B Artery
The ventricles pump blood into the arteries regularly about 70 to 80 times a minute. The force of the ventricular contraction starts a wave of increased pressure that begins at the heart and travels along the arteries. This wave, called the pulse, can be felt in any artery that is relatively close to the surface, particularly if the vessel can be pressed down against a bone. Normally, the pulse rate is the same as the heart rate.
