The source-backed, question-specific record explains: The treaty ending the Third Anglo-Mysore War required Tipu to cede territory, pay an indemnity and provide two sons as hostages until payment obligations were fulfilled. The exact names are less central than understanding that two princes were held temporarily as security for the treaty. This evidence establishes the historical relationship required in this Important Battles item. Similar periods, genres or national traditions do not make two battle facts interchangeable. Option A gives Two of his sons were delivered temporarily as hostages and satisfies every condition stated in the question. The remaining choices—All four sons were exiled permanently, His prime minister alone was detained and No hostage condition existed—do not satisfy the complete requirement. Replaying that method for this Important Battles question confirms Two of his sons were delivered temporarily as hostages without relying on option position.
