ANSWER
The correct option is D.
Jogging in a swimming pool is also called aqua jogging. Aqua jogging involves wearing a flotation device around one's middle and then moving the arms and the legs in a running motion in the deep end of the swimming pool. It is a perfect method for staying fit when injured without impacting the legs. During aqua jogging, the water gives support by taking part of the body weight off the knees and the joints while allowing one to engage in activities that build muscles around the knees.
