Answer:

The correct answer is option a.

Explanation:

Power output refers to the power exerted at the time of performing physical activities. Power output is one of the best means of determining athletic performance at the time of exercise or any physical activity. When the athlete jumped over the treadmill, his output power enhanced abruptly, while the power input enhanced slowly over a duration of one to two minutes.
