There are obvious real problems with this, and some quibbles.
The biggest problem is the buttons, and it should be obvious to anyone who speaks and writes english relatively well: The question asked doesn’t match the either of the “answer” choices given. “How many pizzas would you like? Yes.” is nonsensical. Of secondary concern are the choices themselves, which are three “radio” buttons, but they could just as easily be a drop-drop menu. It’s a stylistic choice, and to be honest, I’m not necessarily against the radio button approach. The redundancy of having to print “pizzas” after each choice is also a bit lazy, but, they do at least make logical sense.
Perhaps a better way to tackle this might be a two-mode interface, which first asks the user “do you want up to 3 pizzas?” and then, once they click “yes,” ask them how many. It is more involved, and I am not sure it would be worth the “extra” click for users who do, in fact, want pizza(s).
