A: method(yes), constructor(yes), operator(yes)

İt says wrong. What the hell is the answer?

Answer 1

Sometimes Challenge questions come in that aren't correct, or are made by someone who's still learning and doesn't know about some examples/usages.
When your Challenge results are in, check what the answers are, and report that one as incorrect.

Answer 2

There was also destructor. I've chosen 3 of 4. I think i have tried all possible subsets of answers and still could not find the correct set.

Answer 3

I'am still seeing this question and there is nothing i can do about it. Am i the only one who doesnt have a "report" button? (Note: i am using ios 10.3.2)
