It is called a refracting telescope.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
A telescope lens works to magnify distant objects by bending and focusing light rays that enter the lens. This allows the lens to gather more light and bring the image of the distant object into focus, making it appear larger and clearer when viewed through the telescope.
A telescope uses lens and mirrors to collect and focus light from distant object.
A refracting telescope uses the most direct light path, relying on lenses (rather than prisms and mirrors) to provide a focused image of the night sky.Its opposite would be the reflecting telescope.
The list of choices you included with your question doesn't include any part of atelescope that can do that. I would have picked the objective, whether a lens ora mirror.
It refracts (bends) light into a focal point
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
A refracting telescope works just like a magnifying glass. It uses a convex glass lens (to bend light and bring it into focus. This lens is thicker in the center than it is toward its edges, which bends the light more at the edge of the lens than light coming through the center. This allows all of the light to come together at a focus point. The point of focus is where the image is created. If someone looks into the eyepiece, a concave lens magnifies the image Refracting telescopes have two main problems-images are not always clear because the light is being bent and the size of the lens is limited (which limits the power of the telescope).
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.

A refractor is a telescope whose principal focusing element is a lens and collects lots of light from a distant object and brings that light, or image, to a point or focus.
