What does the double equal sign operator $(==)$ do$?$

Use the following statement as a reference for the options below:

i $==$ j

Question $5$ options:

It sets the variable $"$i$"$ equal to the value currently represented by the variable $"$j$"$

It sets the variable $"$j$"$ equal to the value currently represented by the variable $"$i$"$

It checks to see if the values of $"$i$"$ and $"$j$"$ are equal to each other, returning a boolean $"1"$ or $"0"$ representing True or False, respectively

It returns an error because $"=="$ is not a valid operator
