Solution

The correct option is C Shyam>Ram>Karan
Physical activity increases the pulse rate of the body. Higher the pulse rate, higher will be the breathing rate of a person. Shyam who ran for 100m has more pulse rate than Ram, who only walked for 10 minutes and Karan, who is at rest. So the breathing rate is also higher for Shyam than Ram and Karan.
So the correct answer is 'Shyam>Ram>Karan'.
