B Correct answer
Explanation

Oracle Database implements alert throttling to prevent alert flooding. For undo segment alerts, the system sends at most one alert per 24-hour period, even if multiple undo-related issues occur. This prevents administrators from being overwhelmed by redundant notifications for the same type of issue. Options A, C, and D incorrectly state the time period or alert type.
