Correct answer choice is :
C) Vigorous intensity
Explanation:
Vigorous is a representation for something energetic or excited. It appears from the French word vigor, meaning liveliness, activity. An active, physically active person is vigorous, and mental exercises can be vigorous too when they need a lot of thoughtful work. Vigorous-intensity activity is a physical exercise done with a large number of effort. It is the intensity at which you have a considerably higher heart rate and fast breathing. You are only capable to speak in short expressions due to the rapid breathing and work.
