The correct selection is C, D. Partial Copy and Full sandboxes contain production-derived data and are therefore appropriate for meaningful batch-data validation. Partial Copy provides representative samples, while Full provides the highest-fidelity production dataset and is the standard choice when realistic volume and performance characteristics are required. From a testing perspective, the goal is deterministic evidence that the solution behaves correctly under the conditions that matter. Tests should isolate external dependencies, use controlled data, exercise positive and negative paths, and reproduce realistic volume or user behavior where required without making production the first place defects are discovered. The alternatives do not provide equivalent evidence: they either validate only a narrow implementation detail or depend on conditions outside the test ' s control. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (C. Partial Copy sandbox; D. Full sandbox). Applying that rule consistently keeps the implementation aligned with Salesforce-supported lifecycle practices and makes the resulting change easier to review, validate, and operate across environments.
