Tennis instructor: Few tennis players spend much time performing exercises that increase their ability to take oxygen into their lungs, though proper and sufficient oxygen intake is crucial to developing a competitive edge on the court. That is why I recommend a particular yoga course that is designed for athletes at all levels and in all sports.

Which of the following would, if true, most strengthen the argument above?

A. A number of high-profile tennis players have taken the yoga course.
B. Individuals who take the yoga course increase their oxygen intake substantially.
C. Tennis players are more likely to study yoga than are other athletes.
D. The number of professional tennis players who perform exercises that increase oxygen intake has increased over the last 20 years.
E. Professional tennis players who take a yoga course are able to advance more rapidly in the course than are non-professional tennis players.
