The right-hand rule predicts which of the following?

The direction of the force on a charged object moving in a gravitational field.

The direction of the motion of a charged object moving through an electric field.

The speed of a test charge through a magnetic field.

The direction of the force on a charged object moving through a magnetic field.

The direction of the force on a charged object moving through a magnetic field.

Explanation:

When considering the motion of a charged particle in a magnetic field, the important vectors are the magnetic field B, the velocity of the particle v, and the magnetic force exerted on the particle F. The vectors are all perpendicular to each other. As demonstrated by the right-hand rule.
