If the home team's provided ball is not legal, what can the referee do?

In this scenario, if the home team's provided ball is deemed illegal according to the NFHS basketball rules, the referee has the authority to select a legal ball from the visiting team. This ensures that the game can continue seamlessly without an extended delay.

Using a ball from the visiting team is in line with the regulations that prioritize the integrity of the game and compliance with legal specifications for equipment. It also maintains fairness since both teams should have a chance to use a standard, approved ball during the competition.

While other choices may suggest alternative actions, such as pausing the game to find a legal ball or sourcing a ball from the scorekeeper, they do not align with the most efficient and practical solution that ensures the continuity of the game. Allowing the home team to provide a new ball could lead to further delays or complications if they cannot supply one quickly. Thus, selecting a legal ball from the visiting team is the most appropriate action in this context.
