Answer:
d.galaxies are moving away from each other
Explanation:
"a" is incorrect because galaxies don't die per-say
"b" the big crunch is about how the universe might end
"c" is also incorrect because everything in our galaxy stays moving and if it were to stop moving it would shrink and if it were to speed up, it would get bigger (the explanation as to why "d" is the correct answer)
good luck :)
hopefully, this helps
**please let me know if this was wrong**
have a nice day !!
