How can one execute a standalone deployment?

Executing a standalone deployment can be effectively accomplished using Metadata Deployment. This method allows users to deploy metadata components, such as custom objects, fields, and Apex classes, from one environment to another without needing to create a full change set or rely on auto-deployment mechanisms.

Metadata Deployment is particularly useful for developers and administrators who need to make specific changes without affecting other configurations or relying on a continuous integration system. It gives the user control over exactly which components are included in the deployment, thus streamlining the process and minimizing potential issues.

The other options do not directly pertain to executing a standalone deployment in the same sense. Initiating Direct Transfer and Accessing Quick Deploy are more likely associated with different deployment strategies that either simplify or automate the process, and Starting Auto Deploy involves automated processes that may not allow for the granular control that standalone deployments via Metadata offer.
