VS Code and Salesforce DX provide the supported development and deployment tooling for OmniStudio Lightning Web Components associated with DataPacks. Salesforce explicitly states that administrators and developers use Visual Studio Code with Salesforce DX and the Salesforce CLI to manage, develop, and deploy OmniStudio Lightning Web Components between development, sandbox, and production organizations.

This distinction matters because an OmniStudio DataPack can include configuration metadata as well as generated or supporting Lightning Web Component artifacts. When LWC deployment is required, a Salesforce DX project provides the metadata structure, authentication, source management, and deployment commands needed to transfer the components reliably between environments.

VS Code by itself is only the development environment; it does not constitute the complete Salesforce deployment mechanism. Salesforce DX provides the Salesforce-specific project model and deployment capabilities, making option B incomplete. Standard Change Sets aren't the recommended deployment mechanism for these OmniStudio LWC assets, while the ANT Migration Tool represents an older Metadata API deployment approach and isn't the prescribed toolchain for this requirement.

Therefore, the complete supported combination identified by Salesforce is Visual Studio Code together with Salesforce DX.
