Gekata [30.6K]

The correct answer would be option D, All of the above.

Speed is an important component of Tennis, Soccer and Swimming.

Explanation:

Tennis, Soccer and Swimming are the sports which require instant moves with high speed.

  • Swimming is the game which is solely dependent upon speed. The swimmer who has the highest speed will win.

So speed is an important component of all of the above mentioned sports.
