Answer: Dedicated Hosts for using existing per-core licenses and cost reduction.
The correct answer is B, Dedicated Hosts. This option allows customers to use their existing per-core software licenses by providing full control over a physical host dedicated to running their instances. This is particularly beneficial for companies that have per-socket, per-core, or per-VM software licenses and want to reduce costs by applying these licenses to their AWS infrastructure. The other options do not specifically cater to the use of per-core software licenses: Reserved Instances offer discounts for a commitment to use instances over a term, Spot Instances provide spare capacity at variable prices for flexible, interruptible workloads, and Dedicated Instances offer non-shared hosts without the ability to use per-core licenses.
