The platform gives a native tool for this situation. Use B. Clone the change set and re-deploy. Change sets move supported metadata between connected Salesforce environments. The receiving org uses inbound change sets and deployment validation to confirm whether the package can be deployed safely.
The selected answer is stronger because it meets both the functional requirement and the maintainability requirement. In a Salesforce implementation, a solution that only works for one user, one page, or one data sample is not good enough. The correct feature has to behave consistently across the intended profiles, record types, apps, and devices that are part of the design.
The other choices would leave a gap in the implementation. A (Rename the change set, add the changes and re-deploy.) misses the mark because Deployment tooling moves or validates metadata; it does not create the runtime business behavior itself. C (Refresh the test sandbox and re-deploy the change set.) handles a different concern; Deployment tooling moves or validates metadata; it does not create the runtime business behavior itself. D (Update the change set and re-deploy.) is less defensible because Deployment tooling moves or validates metadata; it does not create the runtime business behavior itself. In a real org, the builder should include negative testing as well, proving that the rule does not fire or display outside the intended conditions.
