a. spike the ball

Spike the ball is legal for a volleyball player to do.

To determine which of the actions listed is legal for a volleyball player to do, we need to refer to the official rules of the game. The primary authority for volleyball rules is the FIVB (Fédération Internationale de Volleyball), which governs international play. Additionally, local governing bodies may have their own variations of the rules.

In this case, we need to analyze each option and check its legality based on the rules:

a. Spike the ball: To spike the ball, a player jumps near the net and forcefully hits it downwards towards the opponent's court. Spiking is a legal action in volleyball and is commonly used as an offensive strategy to score points.

b. Touch the net during play: According to the official rules, a player is not allowed to touch the net with any part of their body while the ball is in play. This includes not only touching the net deliberately but also incidental contact. Therefore, touching the net during play is not legal.

c. Hit the ball twice in a row: In volleyball, a player is not permitted to hit the ball twice consecutively, except under specific circumstances. The exception is if the first contact is a block, and the player then has an opportunity for another contact (such as a hit or a set). However, in most cases, hitting the ball twice in a row is not allowed.

d. Cross underneath the net during play: Crossing underneath the net during play is generally illegal. A player is not allowed to completely cross the centerline with any part of their body, interfering with the opponent's side of the court. This rule safeguards both players' safety, ensuring they do not collide or impede each other's movements.

In conclusion, based on the official rules of volleyball, it is legal for a player to spike the ball (option a), while touching the net during play (option b), hitting the ball twice in a row (option c), and crossing underneath the net during play (option d) are all generally illegal.
