Universal Containers has five development teams.

The correct selection is B, D. Consistent coding standards reduce the cognitive effort needed to understand code across multiple teams, while version control provides change history for root-cause analysis. Together they improve maintainability and defect traceability without creating a centralized review bottleneck. From a build perspective, the implementation should be source-driven, reviewable, automatable, and modular. Engineering controls such as version control, package boundaries, static analysis, coding standards, and isolated development environments reduce defects early and make changes easier to understand, test, and promote. The alternatives do not create the same repeatable engineering control: they either postpone defect detection, couple teams unnecessarily, or bypass the package/source model that should govern the change. For this scenario, the decisive point is therefore the platform behavior represented by the selected options (B. Define and follow code standards.; D. Version control system to identify who is generating the bugs.). 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.
