Infrastructure as code (IaC) is the correct option because it allows for the automated provisioning and management of cloud resources through code, which can be version-controlled and reused. This is beneficial for maintaining consistency across multiple environments. Using the AWS Management Console is not ideal for tasks that need to be replicated or version-controlled, as it is a graphical interface designed for manual operations. Although programmatic access via APIs, SDKs, or CLI can also be automated, they do not inherently provide the same benefits of version control and reusability that are core to IaC.
