What was the source of that question? (Jeez I hope I didn't write that one
)
On the real exam, the GC questions are VERY 'trickily' worded, although I'd say they're worded better than this question. I don't think any of the answers are strictly correct, C *might* be but it's worded very ambiguously. I don't think you'll see ambiguous writing like this on the real exam.
