What is the pressure in the left ventricle in the described pathway?

Explanation:
During the described pathway the left ventricle is in its systolic contraction, generating high pressure to eject blood into the aorta. To open the aortic valve and pump blood against the systemic circulation, LV pressure rises to roughly the systemic systolic level, about 110–120 mmHg in a healthy adult. Among the options, 110 mmHg best matches this peak systolic pressure. The other values reflect non-systolic or diastolic states (diastolic LV pressure is much lower, around 5–12 mmHg), so they don’t fit the phase of rapid ejection.
