Final answer:
The volume will be available immediately after taking a snapshot.
Step-by-step explanation:
The correct answer is B. The volume will be available immediately.
Taking a snapshot of an Amazon EBS volume does not affect the availability of the volume. A snapshot is a point-in-time copy of the volume, and it does not interrupt the volume's availability.
Regardless of the provisioned size of the volume, the amount of data stored on the volume, or whether the attached instance is an Amazon EBS-optimized instance, the volume will be available immediately after taking a snapshot.
