  Play the 2.
Considering that South opened 1NT, he must have the Q for this play to make sense.

So if you put on your A, South will have TWO winners established. If instead you play low, then South cannot get a second trick and will have to look elsewhere for his ninth trick. As you can see, he is not going to be able to find it.
