The planet that has the greatest angle between its axis of rotation and the normal to the plane of its orbit is

The axial tilt is defined as the angle between the direction of the positive pole and the normal to the orbital plane. The angles for Earth, Uranus and Venus are approximately 23°, 97°, and 177° respectively.

Hope this helps:)

The planet that has the greatest angle between its axis of rotation and the normal to the plane of its orbit is Uranus.

Most planets are tilted in their orbit but Uranus has the greatest axial tilt of 98 degrees essentially meaning it is spinning on its side. Axial tilt is angle between rotational axis and orbital axis.

The large axial tilt causes the planet's the North Pole to be next to the equator and Astronomers believe that this tilt was caused by a collision with material that may be the size of the earth. The collision which may have occurred once knocked Uranus off of its normal orbital place.

a and b because with the other three, they simplify to something else.
