Automating infrastructure and deployment processes significantly enhances the reliability of deployments in DevOps. This practice reduces the risk of human error that often occurs in manual processes and enables consistency in the deployment environment. Automation ensures that applications are deployed in the same way every time, which leads to fewer unexpected issues and provides teams with the confidence that deployments will behave as expected.

Automation integrates best practices such as Infrastructure as Code (IaC), which allows teams to provision and manage infrastructure through code, ensuring version control, reproducibility, and easier rollbacks if needed. Additionally, it often includes continuous integration and continuous deployment (CI/CD) pipelines that enable faster feedback loops and improve overall software quality, contributing further to the reliability of the deployment process.

The other options would not enhance reliability in the same way; for example, relying on manual testing can introduce variability and delays, while using legacy systems can lead to compatibility and security issues. Restricting team access to source code hampers collaboration and can prevent timely fixes and improvements, detracting from overall reliability in the deployment process.
