Since there are no special requirements in the problem statement other than cost (e.g., workload consistency, specific instance size, future changes), simply select the least expensive plan. Compared to on-demand instances, Reserved Instances (RI) offer discounts of up to 75%, Compute Savings Plans up to 66%, and EC2 Instance Savings Plans up to 72%. In each case, the higher the upfront payment, the greater the discount.

The mention of serverless workload is just distraction. It can be for a new system and meanwhile it may not be commercially or operationally viable to move the current ec2 workload to serverless, so it's normal to continue to run it with cost effectiveness for the next 3 years.

Option C seems better. Because with Option A, provides comprehensive coverage but involves upfront payment and potentially redundant cost coverage if Compute Savings Plans are also being purchased. The combination might be less cost-efficient due to the overlap in coverage.

A because it is said that 3 years ago they optimized costs and came to that conclusion... so just renew reserved instances and for compute use compute plan because that is the best add for serverless...

A Need a Compute Savings Plan for serverless workloads The least expensive way to run EC2 instances for 3 years would be either a Reserved Instance or EC2 Instance Savings Plan.
