In which of the following conditions is a high or wide pulse pressure (> 25% of systolic pressure) common?

Pulse pressure is the difference between systolic and diastolic pressures. A wide pulse pressure means this gap is large, which happens when the heart ejects a lot of blood (high stroke volume) or when arterial compliance is reduced, or both. During strenuous exercise, the body’s sympathetic drive pushes the heart to pump more forcefully, raising systolic pressure as stroke volume soars, while skeletal muscle vasodilation lowers diastolic pressure or keeps it from rising as much. The net effect is a noticeably larger difference between systolic and diastolic pressures, so the pulse pressure becomes wide. Aging can widen pulse pressure over time because arteries stiffen, increasing systolic and usually lowering diastolic, but that’s a chronic change rather than an acute state like exercise. Hypotension tends to narrow the pulse pressure because both numbers are low. Anemia can widen pulse pressure too, due to a high-output state, but the most typical, everyday scenario described here is the acute rise seen with strenuous effort.
