- real, erect and diminished
- virtual, inverted and diminished
- real, inverted and magnified
- virtual, inverted and magnified

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
An astronomical telescope works by having a large objective lens and an eyepiece. It produces a virtual, inverted, and magnified image of distant objects. This is because the objective lens gathers light from distant objects and forms a real, inverted image, which is then magnified by the eyepiece. The final image appears upside down (inverted) and larger (magnified) than the original object.
