Which statement is true about the pre-match coin toss?

The statement that each captain is assigned a side of the coin during the pre-match coin toss is correct because it ensures that both team captains understand and agree on the process being followed. This method provides clarity and fairness, as it allows both captains to know exactly what they are calling, whether it is heads or tails, and eliminates confusion about who is responsible for making the call.

In a standard pre-match coin toss, typically, the referee will present the coin to the captains and let them know which side corresponds to which team. This assignment helps to reinforce the sportsmanship aspect of the event, as both teams can equally participate in deciding the initial serving or court side, setting a collaborative tone before the match begins.

The other statements have inaccuracies that do not align with typical pre-match procedures in volleyball. For instance, it's not customary to determine who calls based on the distance traveled to the venue or to restrict the toss call exclusively to the home team's captain. Additionally, while the second referee may observe the toss, it is generally the head referee who conducts it.
