Answer:

The correct answer is option 'D':During ventricular systole, the left ventricle generates more than 120 mmHg .

Explanation:

A blood pressure of 120 mm Hg means that during the ventricular systole the blood leaves the ventricles to the rest parts of the body the pressure that it exerts on the walls of the arteries equals pressure exerted by a column of 120 mm of mercury. At the peak flow the pressure should be just exceed 120mm Hg in order to initiate circulation. The excess pressure is needed as we need to overcome the resistance of the blood in the arteries that is at a pressure of 120 mmHg
