Which of the following techniques enables automation and iteration of code releases?

→ CI/CD (Continuous Integration / Continuous Deployment) is a DevOps methodology that automates the building, testing, and deployment of code. It allows teams to iteratively release updates and improvements in a reliable and scalable manner.

Why the other options are incorrect:

A: Virtualization provides environment emulation but doesn’t manage code releases.

B: Markdown is a documentation tool — unrelated to deployment automation.

C: Code isolation refers to modular programming, not automation pipelines.
