An instrument for viewing distant objects in space.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Telescope.
Telescope is the correct answer because it is specifically designed to view distant objects in space, like stars and planets. The other options do not fit: Microscope is for magnifying tiny objects, Spectrograph is for analyzing light, and Binoculars are for viewing distant objects on Earth, not in space. Hence, Telescope is the most appropriate choice.
