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 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'.

I think the answer is A) return $this->m() . 'ello'. It makes sense to concatenate 'h' from $this->m() with 'ello'.
