HELP DUE SOON Why must many of the telescopes that detect invisible wave, such as infrared, microwaves, and gamma rays, be placed in space?

a Most radiation reaching Earth from space is blocked by the atmosphere. Therefore, some telescopes must be placed above the atmosphere.

b There are not enough places on land to build observatories that hold large telescopes.

c All telescopes must be placed in space. There are not telescopes on land.

d The waves in the electromagnetic spectrum are all too small to be detected by telescopes on land. Therefore, in order to see any EM radiation, telescopes must be placed in space.
