One Significant Feature of the Lagrange Points Produced by the Sun

One significant feature of the Lagrange points produced by the Sun and Jupiter is that

A) they are regions of reduced gravitational force in the asteroid belt from which asteroids can escape, producing the gaps within the belt.
B) gravitational forces combine to trap asteroids at these points.
C) gravitational forces combine to enhance the overall force on particles passing through them, accelerating them out of the solar system.
D) they are points of maximum gravitational force near Jupiter, where the major moons Io and Europa are held.
