Why are you guessing? Why aren't you studying your text materials -- or at least researching on Google?

"An autosome is a chromosome that is not an allosome (i.e., not a sex chromosome). Autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell, whereas members of an allosome pair may differ from one another and thereby determine sex.

The site you sent me I can't open it.
So your saying that B is right and D is wrong?
I did do research but found nothing compared to my question.

You just needed to remove the "Wikipedia"" part from the end of that link for it to work.
