Explanation:

The statement "Optical telescopes are made using lenses" is true.

• Optical telescopes use lenses to produce a magnified image of a distant object.
• Two lenses are used in telescopes, one works as an eye piece and the other magnifies the image. Eye piece helps in focusing the magnified image.
• Concave lens are converging lens, that means it converges the light rays to a point called the focus. As the light rays fall and are reflected at different angles it helps in focusing the light.
• It produces virtual, erect and magnified image when the position of the object is less than the focal point.
