Explanation

A is correct because Infrastructure as Code (IaC) is exactly the practice of defining and provisioning infrastructure (servers, networks, databases) through machine-readable configuration files rather than manual processes - tools like Terraform, Pulumi, and AWS CloudFormation are prime examples.

B describes cloud provisioning from the provider's side - that's how AWS or Azure allocates resources to customers, not IaC itself. C defines cloud infrastructure components (compute, storage, networking) - these are the targets of IaC, not the practice itself. D describes monitoring/observability - collecting and analyzing infrastructure telemetry is a separate discipline entirely.

Memory tip: Think of IaC as "treating your servers like software" - you write code to describe what you want, commit it to version control, and let automation build it, just like deploying an app.
