Speed is an important component of which of the following sports?

Speed is indeed a critical component in tennis, soccer, and swimming, making the choice that includes all these sports the most accurate.

In tennis, players need speed to quickly move across the court to return serves and volleys. Quick bursts of speed can also allow a player to position themselves advantageously to hit the ball with power and precision, significantly impacting the outcome of the match.

In soccer, speed is essential both in terms of running with the ball and making breaks to get open for passes or to chase down opponents. Fast players can create scoring opportunities by outpacing defenders and can also recover defensively to thwart attacks.

Swimming relies on speed for competitive success as well, where the ability to swim faster than opponents determines race outcomes. Swimmers train extensively to enhance their stroke efficiency and overall speed in the water.

Given that speed plays a vital role in all three sports, the inclusion of every sport in the choice confirms the comprehensive importance of speed across varied athletic activities.
