The correct answer is
A For every 3 families in the neighborhood, 2 families own only one car

It is stated that the relations are 2:3 in the sense of one car : more cars. That means that for every two families with one car, there are three families with more cars. In that sense, every 4 families will have one car while six families will have more cars, and so on and so forth.
