If a player substitutes a ball, what conditions must be met?

When a player substitutes a ball during play, it is essential for the player to understand the specific conditions regarding the original and substitute balls. The correct answer reflects that a player may choose to use either the original ball or a substitute ball when making this decision.

This flexibility allows players to select the best option for their situation, adhering to the rules that permit the substitution of a ball under various circumstances, such as when a ball is lost or damaged. For instance, if a player's ball is deemed unplayable or they choose to replace it due to specific conditions (like a water hazard), they can opt for a substitute instead of needing to locate the original ball.

The other choices do not accurately represent the rules governing ball substitution in the game. For example, notifying an opponent is not a requirement for substitution, nor is it necessary to use the original ball exclusively. Players are also not obligated to always use a new ball; they can rather replace it with an existing ball that meets the necessary conditions of play. Thus, the player's ability to use either the original or a substitute ball captures the essence of ball substitution rules effectively.
