Biology mcq

Hi, please can i have help on this question? The answer I worked out is not appearing, i basically did the total number of cells divided by the cells in prophase metaphase and anaphase because that is when the chromosomes can be seen as two chromatids but the answer is B? Thanks

Here is the question: https://app.gemoo.com/share/image-annotation/581897613035982848?codeId=MpE66eyQqLnmV&origin=imageurlgenerator

basically during anaphase the chromatids spilt to each of the poles of the cell so it doesnt appear as 2 chromatids.

so you do (prophase + metaphase) / total x 100 to get ur answer


hope this helps
