Text SolutionText solutionverified iconVerified

Height of image depends upon the magnifying power to see a 20 times taller object, as the angular magnification should be 20 and we observe angular magnification. Option (c) would not be very correct as the telescope can be adjusted to form the image anywhere between infinity and least distance for distinct vision.
Suppose that the image is formed at infinity. Then, the observer will have to focus the eyes at infinity to observe the image. Hence, it is incorrect to say that the image will be appear nearer to the observer.
