Explanation

Interval training is a type of training mainly used in athletics, cycling, and swimming, in which after warming up, great efforts are made for a certain time separated by a break. That is to say, that interval workouts require the body, give it a short break and return it to an effort. This type of training allows the body to adapt to a short recovery and try harder and harder. Therefore, option B "Sprinting 100 yards, resting, sprinting 200 yards, resting, sprinting 300 yards, resting, sprinting 200 yards" is an interval training because you have to do one hundred, two hundred and three hundred yards sprints, separated by breaks which means effort increases but this includes intervals or breaks. So, the correct answer is B. Sprinting 100 yards, resting, sprinting 200 yards, resting, sprinting 300 yards, resting, sprinting 200 yards.
