Answer: Option D

Solution (By Examveda Team)

This question is about different types of joins in MySQL, which are used to combine data from multiple tables.

Let's break down the options:

Option A: CARTESIAN JOIN
This is a join where every row in the first table is combined with every row in the second table. This can result in a very large result set and is rarely used intentionally.

Option B: CROSS JOIN
This is the same as a CARTESIAN JOIN. It produces all possible combinations of rows from the two tables.

Option C: INNER JOIN
This join only returns rows where there is a match between the join columns in both tables.

Option D: RIGHT JOIN
This join returns all rows from the right table and matching rows from the left table. If there is no match in the left table, the right table's rows will still appear with NULL values for the left table's columns.

Therefore, the answer is Option D: RIGHT JOIN.

Explanation:
A RIGHT JOIN ensures that every row from the "right" table appears in the final result, even if there's no corresponding match in the "left" table.

Think of it like this:
Imagine you have two tables, one with customer names and another with orders.
A RIGHT JOIN with "orders" as the right table would include all orders, even if some customers have not placed any orders yet. The output would include NULL values for the customer details in cases where an order doesn't have a corresponding customer.
