An object is situated to the left of a lens. A ray of light from the object is close to and parallel to the principal axis of the lens. The ray passes through the lens. Which one of the following statements is true?

The ray passes through a focal point of the lens only if the lens is a converging lens.

The ray passes through the lens without changing direction, no matter whether the lens is converging or diverging.

The ray crosses the principal axis at a distance from the lens equal to twice the focal length, no matter whether the lens is converging or diverging.

The ray passes through a focal point of the lens only if the lens is a diverging lens.

The ray passes through a focal point of the lens, no matter whether the lens is converging or diverging.
