Which of the following join is also called as an 'inner-join'? Correct Answer Equijoin

The join known as an 'inner-join' is also referred to as an Equijoin. An Equijoin is a type of join in SQL that combines rows from two or more tables based on a related column between them, using the equal (=) operator. It selects only the rows for which there is a match in both tables. Option C is the correct choice for the join also known as an 'inner-join.' Options A and B are different types of joins, and Option D states that none of these terms refer to an inner-join.
