Systolic pressure and diastolic pressure are defined by which statement?

Explanation:
Arterial pressure has two phases tied to the heartbeat: systole, when the heart contracts and pumps blood, and diastole, when the heart relaxes between beats. Systolic pressure is the pressure in the arteries during contraction, peaking as the ventricle pushes blood into the aorta. Diastolic pressure is the pressure when the heart is at rest between beats, representing the minimum arterial pressure before the next beat. This pairing—systolic during contraction and diastolic during relaxation—is why the statement is correct. The other options either describe only one phase or refer to an averaged measure over time rather than the two distinct pressures.
