The key considerations are: The company needs flexibility to change EC2 instance types and families every 2-3 months. This rules out Reserved Instances which lock you into an instance type and family for 1-3 years. A Compute Savings Plan allows switching instance types and families freely within the term as needed. No Upfront is more flexible than All Upfront. A 1-year term balances commitment and flexibility better than a 3-year term given the company's changing needs. With No Upfront, the company only pays for usage monthly without an upfront payment. This optimizes cost.

"EC2 Instance Savings Plans give you the flexibility to change your usage between instances WITHIN a family in that region. " https://aws.amazon.com/savingsplans/compute-pricing/

Only Compute Savings Plan allows you to change instance family.

" needs to change the type and family of its EC2 instances". that means B I think.

B is the right answer

B is correct.. 'EC2 Instance Savings Plans' can't change 'family'.

Correct B. To change 'Family' always Compute saving plan, right?
