Provide an appropriate response.One way to measure a person's cardiofitness is to calculate how many METs, or metabolic units, he or she can reach at peak exertion. One MET is the amount of energy used when sitting quietly. To calculate ideal METs, we can use the expression: 
Researchers recommend that a person reach approximately 85% of his or her MET when exercising. Calculate 85% of the ideal MET for a 65-yr-old woman. Then refer to the following table. What activity can the woman do that is approximately this value? 
A. 6.25; Mowing lawn B. 5.313; Ballroom or square dancing C. 5.313; Walking D. 6.25; Swimming
