Infrastructure as Code (IaC) is the correct answer because it allows businesses to automate the deployment and configuration of their cloud infrastructure, ensuring consistency and repeatability. It declaratively specifies resources in configuration files, which can be version-controlled and reused. This contrasts with the AWS Management Console, which provides a web interface for manual operations, and programmatic access via SDKs or CLI which requires writing custom scripts for each operation without providing the inherent benefits of tracking and standardization that come with IaC.
