What is a primary function of Workbench?

The primary function of Workbench is to describe, query, manipulate, and migrate data and metadata. Workbench is a powerful web-based tool that provides developers and administrators with a robust interface for interacting with Salesforce data. It allows users to execute SOQL and SOSL queries to retrieve data, perform data manipulation operations like inserts, updates, and deletions, and also handle Salesforce metadata. This makes it highly valuable for tasks involving data import/export, examining data structures, and migrating changes between different Salesforce environments.

The other options, while they do mention functionalities that can be related to Salesforce, do not encompass the main capabilities that Workbench offers in the context of data and metadata management. The creation and deletion of records, user access management, and running Apex code are functionalities present in Salesforce but not the central focus of what Workbench is typically used for.
