Option A is incorrect as the cache option instructs Oracle to return values in order from the cache, not in the order of user requests.
Option B is incorrect as the cache option does not affect the minimum or maximum values of a sequence.
Option D is incorrect as the highest value for a cached number depends on the specific cache size set for the sequence.

Option C is correct as once a value has been generated and cached, it cannot be regenerated until the sequence begins a new cycle. This is because cached sequence values are stored in memory, and once a value is retrieved from the cache, it is considered "used" and cannot be reused until the cache is replenished with new values.
