What do refracting and reflection telescopes have in common?

a. They both use a convex lens in the eyepiece to focus light.
b. The light rays in both are refracted but not reflected.
c. They both use mirrors and lenses to collect lots of light.
d. The light rays in both are reflected but not refracted.

None of the above options accurately describe what refracting and reflecting telescopes have in common. One possible answer could be:

Both types of telescopes are used to observe distant celestial objects and collect more light than the naked eye. They both rely on the principles of optics to enhance the clarity and magnification of the images formed by the incoming light. However, the specific optical components and designs used in refracting and reflecting telescopes differ significantly, leading to different advantages and limitations in their performance.
