Enthuware

My question from enthuware.ocpjp.v17.2.1266,
how this answer is correct on this software, upon checking on chatgpt below statement says compiler error and also in IDE.
"If a and b are of type boolean, the expression (a = b) can be used as the condition expression of an if statement."

I am not sure I understand your question. Which option exactly are you doubting?
