A Join
Suggested answer: D

Explanation:

The data that you analyze in Tableau is often made up of a collection of tables that are related by specific fields (that is, columns). Joining is a method for combining data on based on those common fields. The result of combining data using a join is a virtual table that is typically extended horizontally by adding columns of data.

For example, consider the following two tables originating from a single data source:

We can combine these 2 tables, simply by joining the tables on ID to answer questions like, 'How much was paid in royalties for authors from a given publisher?'. By combining tables using a join, you can view and use related data from different tables in your analysis.
