In the sport of cricket, a team consists of eleven players on the ground during play. This is a fundamental rule of the game, defining the active participants for batting, bowling, and fielding. Each team fields eleven players, with one designated as the captain. The objective is for one team to score more runs than the other, or to dismiss all opposing batsmen.
Option B, 11, is the correct answer, representing the standard number of players actively participating for a team on the field. Options A (10), C (13), and D (15) are incorrect. While a squad might comprise more than eleven players (e.g., 15 for a tournament squad), only eleven are permitted on the field at any given time. Ten players would leave a team short, while thirteen or fifteen would exceed the legal limit, disrupting the game's structure.
