The key idea is what left ventricular ejection fraction (LVEF) measures and what its normal range looks like. LVEF is the percentage of blood the left ventricle pumps out with each heartbeat, and it’s calculated from measurements on an echocardiogram using how much blood is in the ventricle at the end of diastole versus after it contracts. A typical normal range is about 55–70 percent. Having an LVEF around 60 percent means the heart’s systolic function is preserved — the ventricle is pumping a normal share of its blood with each beat.

Among the options, 60 percent sits squarely within that normal range, making it the best fit for a normal systolic function result. The other values indicate different levels of dysfunction: 75 percent can be normal or toward the high end of normal, 30 percent reflects severe systolic dysfunction, and 45 percent indicates mild-to-moderate impairment.
