C. To get a clearer view without the atmosphere of Earth.
Explanation: Earth's atmosphere blurs and distorts images (turbulence/"seeing") and blocks or absorbs large parts of the electromagnetic spectrum (X‑rays, much UV, many infrared bands). Putting telescopes in space avoids those problems so you get sharper images and access to wavelengths you can't observe well from the ground.
(Why not the others: being a bit closer to distant objects is negligible, telescopes don't fundamentally need vacuum to "work," and satellites are not placed in orbit to land on the Moon.)
