Solution

The correct option is A Systole of the left ventricle
The mammalian aorta carries oxygenated blood from left ventricle to different parts of the body. The blood pressure of the aorta is maximum during the systole (contraction) of the left ventricle. As the ventricular pressure increases, the valves guarding the aorta are forced to open, allowing the blood in the ventricles to flow.
