Answer: C

Explanation:

Combining data means connecting to two or more data sources, shaping them as needed, then consolidating them into a useful query. When you have one or more columns that you’d like to add to another query, you merge the queries.

Note: The RELATEDTABLE function is a shortcut for CALCULATETABLE function with no logical expression. CALCULATETABLE evaluates a table expression in a modified filter context and returns A table of values.
