Final answer:
In the Web UI for worksheets, you can select a Virtual Warehouse, a Schema, and a Database, which are essential components for data management and query processing within a data warehouse tool. Thus, the correct option is B.
Step-by-step explanation:
On the Web UI for each worksheet, you can select the following options: B. Virtual Warehouse, E. Schema, and F. Database. When you are working within a data warehouse tool's interface, you're often provided with the ability to configure settings and preferences that are critical to your tasks of managing and querying data.
The Virtual Warehouse is a crucial component allowing you to scale computing resources up or down depending on the need for processing data. The Schema lets you organize and structure the databases, defining how the data is stored and accessed. Lastly, the Database is the collection of schemas, including your datasets, views, and other data structures necessary for your work.
Options such as Role, User, and Table are not typically selected from the Web UI for each worksheet but may instead be configured in different parts of the platform or in the context of permissions and access control. (Option B).
