Solution

The correct option is A the amount of blood that enters during heart contraction.
The left ventricle needs and exerts more pressure than the right ventricle because it is responsible for delivering blood to most parts of the body that need oxygenated blood in order to function. The right ventricle, on the other hand, only does a little effort since it only delivers deoxygenated blood. Therefore, the right ventricular and pulmonary artery peak systolic pressures are lower than the comparable left-sided pressures.
So, the correct option is 'the pressure developed during contraction'.
