Which option represents the aerobic exercise intensity guideline of 50-60% HRmax?

The concept here is matching exercise intensity to heart rate using a percent of maximum heart rate to define the aerobic training zone. The 50-60% HRmax range represents a moderate-intensity aerobic zone, where enough effort is made to stress the cardiovascular system while oxygen delivery to muscles can meet the energy demand. This makes the activity sustainable for longer periods and effective for improving cardiovascular endurance and fitness. The other options describe intensities that are either too low to provide a meaningful aerobic stimulus, or too high (near maximal or vigorous) to be considered the standard aerobic guideline.
