Answer 'C'
Hypothetical: You are a first-year MTC teacher. While proctoring a state test another teacher comes in the room and tells the students, "Question 12 is tricky. Be careful. Answer 'c' is incorrect." The teacher leaves and the students go back to the test, presumably not answering 'c' on question 12. What do you do?

And, as an added bonus, if you report it, the kids will most likely get another week or two of class to prepare for the (make-up) test! Everybody wins!
In that case, I would motion the official administrator to the doorway, tell her/him that I think that they should fill out an incident report form, and when the next teacher comes to relieve me at the end of my planning block, leave without looking back or feeling guilty -- that's all I can do, because the designated proctor and the designated administrator are the only two allowed to make the judgement call to fill out the form.
