hey plz make your question clearly then text me or comment
B. is the correct answer I think
oo, The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right. You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars.
i hope you will get some knowledge from here❣
