C. The entity should consider whether a practical limit has been reached.
According to IFRS 8, if the number of reportable segments increases above ten, the entity should consider whether a practical limit has been reached, and it may need to aggregate operating segments in order to maintain the relevance and usefulness of the disclosed segment information without making it excessively detailed. However, it does not mandate a strict limit of ten segments; rather, it suggests that when the number exceeds ten, the entity should assess whether the additional detail becomes too complex or cumbersome for users of the financial statements. If so, the entity may choose to aggregate or combine certain segments to present more meaningful information.
