A) in the inner solar system. Sunlight, and the solar wind acting over billions of years, have pushed them out past the orbit of Pluto.
B) in elliptical orbits extending out to tens of thousands of astronomical units, and gravitational interactions with the giant planets have circularized their orbits into a band beyond Pluto.
C) exactly where we see them now, in a band beyond the orbit of Pluto.
D) between the orbits of Jupiter and Neptune. They were flung out beyond Pluto by gravitational interactions with the giant planets.
