Answer #1

Answer- option (C) The fraction of heavy nuclei in the Universe.

The Big Bang theory predicts that the early universe was a hot and dense place and soon it expand and becomes cool. Microwave background is remnant heat of that time and fluctuation are due to uncertainity principle. Hence option b and d are testable prediction of Big Bang. Option a is also testable prediction since maximum part was hydrogen initially and it was chages to helium.

I will be glad to see your comment if you have any query. Thanks...
