I'm surprised they even included B and C as options. Those are just nonsensical. D is the only one that makes any sense. Time to move on to the next question!
B is definitely not the right answer. Using '+==' is not a valid comparison operator in most programming languages. I'm leaning towards D, but I'll double-check the other options just to be sure.
Answer A is incorrect. The '==' operator checks for value equality, not variable equality. The correct answer is D, which uses the '===' operator to check for both value and type equality.
