Which evidence supports the big bang theory? A. Planetesimals form in debris disks.
B. Most galaxies are moving toward us.
C. Uniform background radiation is detected in every direction.
D. Galaxies spin faster than they should based on visible matter.

The correct answer to the following question will be Option C.

Explanation:

The above given theory seems to be an astrophysical concept of something like the visible universe from those in the early observed times to its corresponding large-scale development.  Technical calculations and requirements including its expanding universe of that same universe put the Big Bang between about 13.8 hundred million years ago, which would also be known to be the period of the solar system.

So other choices are not related to the given theory. So that Option C would be the appropriate choices.
