Answer: C.) steady state theory
Explanation:
Steady State Theory is based on the so-called "Perfect Cosmological Principle," according to which the Universe is homogeneous, isotropic and immutable. This hypothesis did not deny the expansion of the universe but rather believe in the continuous production of matter to counterbalance the expansion observed, keeping the average density constant. This theory was proposed by Herman Bondi, Thomas Gold, and Fred Hoyle, in 1948. The steady-state theory has lost almost all its adherents when it was discovered the cosmic background radiation, which this theory could not explain.
