Correct Answer

Explanation

The result of the code is '105'.
In JavaScript, the + operator has two different meanings depending on the type of the operands.
If at least one of the operands is a string,
the + operator performs string concatenation.
In this case, the first 5 is converted to the string '5',
and the second 5 is also converted to the string '5', so the final result is '105'.
