Which statement best describes Light Intensity characteristics?

Explanation:
Light intensity is the easiest level of aerobic activity, reflected by low energy expenditure, a gentle effort, and only a small increase in heart rate. It typically falls around 1.6 to 2.9 METs, which means the body isn’t using much more energy than at rest. On the Borg RPE scale, light activity is usually rated around 9 to 11, signaling you can talk in sentences without being out of breath. In terms of heart rate reserve, light intensity engages about 30 to 39% of HRR, showing only a modest lift above resting conditions. The statement matching these three measures—METs 1.6–2.9, RPE 9–11, HRR 30–39%—best describes light intensity. The other options imply more demanding effort (moderate or vigorous) or mix a lower RPE with higher energy use, which doesn’t fit light activity.
