Why Does No Major Planet Orbit the Sun at the Location

Why does no major planet orbit the Sun at the location of the asteroid belt?

A) One such object did form there but was destroyed by a collision with an early comet; the asteroid belt is the debris from the collision.
B) Jupiter''s gravitational pull stirred up the planetesimals, preventing them from coalescing into a single large object.
C) In the early solar nebula, the temperature that close to the Sun was too high for rock or iron to condense into solid form.
D) Three Earth-sized planets did form there, but they destroyed each one another by mutual collisions; the asteroid belt is the debris from these collisions.
