C. 92 The chromatin material duplucated during the S phase of interphase. During prophase it condenses into the chromatids. 100%

C. 92
During prophase the chromosomes are double-stranded; they have two chromatids apiece. They are not separated from each other until anaphase. Since we have 46 chromosomes, there are 92 chromatids in prophase.
Note, D. is NOT the correct answer because the DNA is already doubled when prophase begins.
I am 100% sure that the answer is C.

C ...the 1st reply says they move to opposite poles in prophase...this is wrong..they do that in anaphase!!! just thought i'd make that clear
