Concept:
India hosts several well known football tournaments, and it helps to be able to separate them from tournaments held in other sports that carry similarly styled names.
Explanation:
The I-League is a top division football league in India, the Durand Cup is the oldest football tournament in Asia and third oldest in the world, and the Bardoloi Trophy is a football tournament held in Assam named after Gopinath Bardoloi. The Irani Trophy, however, is a cricket tournament played between the Ranji Trophy champion and the Rest of India team, making it unrelated to football.
Final Answer:
The tournament that is not a football event is the Irani Trophy, option B.
