Option A equi-join

Explanation:

In SQL, we can always combine two or more tables based on a common value shared by the tables. One way to join the tables is the equi join. This is a type of join that can combine tables based on the common values shared by some specified columns in the target tables.

The way to write the equi-join query is as follows:

SELECT *

From Table1, Table2

WHERE TABLE1.ColumnA = TABLE.ColumnB
