Final answer:
The correct answer is option A. The status of an entitlement with future start and end dates upon activation is 'Not started' as it awaits the commencement of its validity period.
Step-by-step explanation:
When you create and activate an entitlement with start and end dates set in the future, the status of the entitlement would be Not started. This is because the entitlement period has not yet begun.
Activation of an entitlement simply means that it has been set up and is ready to be utilized once its validity period begins. Until the start date is reached, the entitlement remains in a Not started state as it awaits the commencement of the validity timeframe for which it has been specified.
