A distractor invented on the way to the lesson diagnoses nothing. The useful wrong options are the mistakes last year's class actually made, written in the words they used, so the count against each one names the misconception.
Put the question in twice, one after the other. Run the first copy, and if the class splits, do not say who is right. Show them the split and give them two minutes to argue it out with the person next to them. Then run the second copy. If the discussion worked, you will see the answers move. Both rounds are saved, so you can put the two charts side by side in the summary afterwards.
Use the quiz type where you want effort and a bit of pace, and plain multiple choice where you want the truth. The moment an answer is marked right or wrong, some of the class starts guessing at your intent instead of reporting theirs.
There is no sign-in, no name on an answer and nothing verifying who is holding the phone. That is deliberate, and it is exactly why students answer honestly — but it means these results are evidence about the class, never a record about a student.
A check that changes nothing in the next ten minutes trains the class to answer carelessly. Reteach the split, or say out loud what you are moving to next lesson because of it.
