Which of the following is a correct reason to apply test automation?

Test automation provides the most value when applied to tasks that are performed frequently and are repetitive in nature, such as regression testing. Automating these tasks saves significant time and effort over the long term, reduces the likelihood of human error, and frees up testers to focus on more complex, exploratory testing. The repetitive nature of the tasks ensures a high return on the initial investment required to create and maintain the automation scripts.

A. A new tool's launch is not a valid business or technical reason to start automation; the need should drive the tool choice.
C. While ease is a factor, the primary driver should be the value and ROI, not just how simple the task is to automate.
D. The cost of a tool is a consideration, but the decision to automate should be based on overall benefit, not just a low purchase price. ---
