  "Savings Plans are a flexible pricing model that offer low prices on Amazon EC2, AWS Lambda, and AWS Fargate usage, in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a 1 or 3 year term." - That already excludes A and B. The question requires to "keep network latency between the services low", which can be achieved by connecting the Lambda functions to the private subnet that contains the EC2 instances. C is the answer.

  Implement Compute Savings Plan because it applies to Lambda usage as well, then connect the Lambda functions to the private subnet that contains the EC2 instances

  A Compute Savings Plan covers both EC2 and Lambda and allows maximizing savings on all resources. Optimizing Lambda configuration reduces costs. Connecting the Lambda functions to the private subnet with the EC2 instances provides direct network access between them, keeping latency low. The Lambda functions are isolated in the private subnet rather than public, improving security.
