In a speech delivered to parents on the launch anniversary of the "let's move" program, michelle obama made this claim:
"so we're making some real progress here. we're gaining momentum. but as far as we've come, when nearly one in three kids in this country is still overweight or obese then we've still got a long way to go."
which of these statements shows an acknowledgement of a counterclaim to her position?

a) "all of us desperately want to keep our kids healthy. but often, we just don't know how. kids don't come with an instruction manual. and while we all get plenty of advice to make sure our kids eat well and stay active what does that really mean? "
b) "and through let's move cities and towns, 500 mayors have committed to tackling obesity in their communities. they're building bike paths, they're planting gardens, they're starting youth sports leagues and so much more."
c) "and today, we're seeing better, clearer labels on beverage cans and many other products in our grocery stores. you asked for better food in your kids' schools—the kind of balanced meals you're trying to make at home."
d) "i didn't know a single child in my neighborhood who was allowed to eat whatever they wanted whenever they wanted. if you wanted a snack, you'd have to ask permission and whatever you got was limited."
