In a Continuous Integration (CI) pipeline, what is a key benefit of using automated builds?

The key benefit of automated builds in a CI pipeline is ensuring consistent and reproducible builds. Option C is correct because automation eliminates the variability introduced by manual processes, guaranteeing that each build follows the same steps, uses the same dependencies, and produces artifacts that are predictable and testable.

Option A (minimizing server costs) may be a side effect but is not the primary advantage. Option B (eliminates coding errors) is inaccurate—automated builds do not prevent developers from writing faulty code; instead, they surface errors earlier. Option D (reduces code redundancy) relates more to code design than CI pipelines.

Automated builds are fundamental to DevOps and platform engineering because they establish reliability in the software supply chain, integrate seamlessly with automated testing, and enable continuous delivery. This practice ensures that code changes are validated quickly, improving developer productivity and reducing integration risks.
