mmx,
Stop posting all the questions of NBME on this forum ! Please, stop ! When I took that test I had to help myself, nobody helped me.
You don't have the right to post these questions, when you bought them you did sign an agreement. Why do you want to influence other candidats' result of their assessment tests?
You can't continue to do it. If you want to be helped by other readers on this forum, why don't you post directly :" MNBE question, please help!".
By the way, the cporrect answer is C: inhibition of thyroidal peroxidase activity.
So long for now , matoka

I met a question asking about PTU(propylthiouracil) mechanism. The answer is PTU inhibits thyroid peroxidase, therefore inhibits iodide ----> iodine.

I guess they are listed under the same column, so methimazole acts the same.

Answer: C.
