Which of the following is considered best practices when using definition files for the provisioning of Linus servers to the cloud?

Build automation refers to automating software compilation and artifact creation pipelines, not the provisioning of cloud server infrastructure.

WARNING - the marked correct answer B (Container orchestration) does not align with the question stem, which asks specifically about definition files for provisioning Linux servers to the cloud. Container orchestration (e.g., Kubernetes) manages containerized workloads, not server-level provisioning. The technically accurate best-practice answer for this scenario is C (Infrastructure as Code), using tools such as Terraform, Ansible, or AWS CloudFormation - this appears to be a question error.

Infrastructure as Code is actually the industry-standard best practice for using definition files to provision Linux servers in the cloud - this choice appears to be the intended correct answer despite the marked answer.

Continuous integration is a development practice focused on frequently merging and testing code changes, not on provisioning server infrastructure.
