North opens 1NT. What do you respond?

With 12 points and a 4-card ♠ suit this fits the model for Stayman.

But thinking a little further, with this 4-3-3-3 distribution you have no ruffing values whatsoever. So even if partner also has 4 ♠s there might not be an advantage in playing the suit contract. So for this specific distribution you ignore your 4-card Major and just bid 3NT.
