what do scientists believe provides evidence for the big bang theory?
a. the gradual spreading of the ocean floors along plate boundaries
b. the presence of cosmic microwave background radiation
c. the presence of the main asteroid belt
d. the core accretion theory of planet formation

Explanation:

Cosmic microwave background radiation is considered a key piece of evidence for the Big Bang Theory. It is thought to be the residual heat from the Big Bang, spread throughout the universe. Ocean floor spreading relates to plate tectonics, the asteroid belt is part of the solar - system formation, and core accretion theory is about planet formation, none of which directly support the Big Bang Theory.

Answer:

B. The presence of cosmic microwave background radiation
