Option B looks like the correct answer. We need to call the $f() function, which is assigned to $this->c, to get the desired output.

Yes, that makes sense. We need to call the function assigned to $this->c.

I think option B is correct. We should return $f() . 'ello'.

Ha! Option D is clearly the way to go. I'm just going to return $y . 'ello' and hope the professor has a sense of humor.

Hmm, that's an interesting point. But I still think A) makes more sense because we need to access the method $this->m() to get 'h'.

I'm going with Option C. Returning 'h' from $this->m() and concatenating it with $this->ello seems like the easiest way to get 'hello'.

Option C is the correct choice. It combines 'h' from $this->m() with $this->ello to output 'hello'.

Option A looks good to me. Concatenating the return value of $this->m() with 'ello' should output 'hello'.

I disagree, I believe the correct answer is B) return $f() . 'ello'. We need to use the variable $f to output 'hello'.
