      The correct answer is: D. To combine data from related tables.

      A JOIN operation in SQL is used to retrieve data from two or more tables based on a related column between them. It allows you to combine rows from these tables, making it easier to analyze and work with interconnected data. For instance, if you have a table for customers and another for orders, you can use a JOIN to get customer information alongside their orders. If you need further clarification or examples, feel free to ask!
