Which of these items provide evidence supporting the Big Bang theory select the correct two items

The two items that provide evidence supporting the Big Bang theory are:

1. Cosmic Microwave Background Radiation: This is electromagnetic radiation left over from the early stages of the universe, about 380,000 years after the Big Bang. Its discovery in 1964 by two Bell Labs astronomers, Arno Penzias and Robert Wilson, was a crucial piece of evidence for the Big Bang theory.

2. Expansion of the Universe: The observation that galaxies are moving away from each other in all directions and that the universe is expanding is another piece of evidence for the Big Bang theory. This expansion was first proposed by Edwin Hubble in the early 20th century and has been confirmed by subsequent observations and measurements.
