None of the above

Explanation:
Detailed explanation-1: -Recall that blood moves from higher pressure to lower pressure. It is pumped from the heart into the arteries at high pressure. If you increase pressure in the arteries (afterload), and cardiac function does not compensate, blood flow will actually decrease.
Detailed explanation-2: -The systolic blood pressure is defined as the maximum pressure experienced in the aorta when the heart contracts and ejects blood into the aorta from the left ventricle (approximately 120 mmHg).
Detailed explanation-3: -As the left ventricle ejects blood into the aorta, the aortic pressure increases to its peak systolic value. The greater the stroke volume, the greater the change in aortic pressure during ejection.
