What is a Let Serve?

The correct answer to this question is D. Volleyball is a sport that is played using a net and in-lines, just like you would in tennis, but players would not use a racket like you would in volleyball. You would use your arms or hands instead of a racket in order to keep the ball in play. A let serve in volleyball is different from tennis.

A let serve is when the ball hits the net and bounces on the other side of the court. The let serve is actually legal in volleyball, whereas in tennis, the serve would be considered illegal.
