The correct answer is:
systole of the left ventricle
Left ventricle drives blood into the aorta during the ventricular systole. Aorta receives blood directly from ventricles and supplies blood to all the body parts. The greater the stroke volume, the greater the change in the aortic pressure. Hence, blood pressure in aorta will be maximum when left ventricle pumps the blood into the aorta.
