In basketball, how many substitutes are typically available?

In the sport of basketball, a team typically consists of players on the court and a bench of substitutes. According to standard rules, such as those followed by FIBA and the NBA, a team's active roster for a game usually comprises twelve players. Of these, five players are on the court at any given time, leaving seven players available as substitutes on the bench. These substitutes can be rotated into the game to rest starters, adjust strategy, or replace fouled-out players. Therefore, option C is the correct answer. Option A, 5, represents the number of players on the court, not the substitutes. Options B (6) and D (15) are incorrect numbers for the typical availability of substitutes in a standard basketball game.
