Why Do We Think Tiny Quantum Ripples Should Have Been

Why do we think tiny quantum ripples should have been present in the very early universe?

A) The energy released when the strong force froze out of the GUT force caused shock waves that produced ripples in the universe.
B) The shock wave of the Big Bang caused ripples that expanded outward with time.
C) The principles of quantum mechanics require that the energy fields at any point in space be continually fluctuating.
D) The annihilation of matter and antimatter particles caused tiny explosions that produced ripples in the radiation field.
E) The principles of quantum mechanics require that matter and antimatter particles formed from high- energy photons continuously eject energy into the universe causing the ripples.
