The correct answer is A: 8. The ICC Champions Trophy 2025, which is scheduled to be held in Pakistan, will feature eight national cricket teams. This tournament format is typically employed to bring together the top-ranked teams in One Day International (ODI) cricket, making it a high-stakes, relatively short event. The qualification for these eight spots is usually based on performance in the ICC Cricket World Cup Super League or directly from the top positions in the ICC ODI Team Rankings.
Option B: 6 is incorrect. Six teams would be a smaller pool than what is usually seen for a major ICC tournament like the Champions Trophy, which aims to include the most competitive nations.
Option C: 10 is incorrect. A 10-team format is more commonly associated with the ICC Cricket World Cup, which is a longer tournament designed to include a broader representation of cricketing nations beyond just the top eight. The Champions Trophy typically maintains a more exclusive field.
Option D: 12 is incorrect. Twelve teams would be an unusually large number for the Champions Trophy, which is often dubbed a 'mini-World Cup' due to its concentrated number of elite teams and shorter duration compared to the World Cup itself.
