Answer 1

Step-by-step explanation:

1)steady-state theory, in cosmology, a view that the universe is always expanding but maintaining a constant average density.so the answer is B

2)Hubble's law, also known as the Hubble–Lemaître law or Lemaître's law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance.so the answer is A

3)B
