B. But with the names of the worst hurricanes emitted
C. After they have omitted the names of the worst hurricanes
D. The names of the worst hurricanes being omitted
Explanation
The correct answer is: Omitting the names of the worst hurricanes.
The list of hurricane names is reused after a few years, but the names of the worst hurricanes are omitted to avoid sensitivity and respect for the victims of those hurricanes.
This completion provides a clear and logical reason for reusing the list with some exceptions.
