I only
II only
III only
II only

Correct Answer: A

Explanation:

. Chromosomes start out as identical sister chromatids. These exchange DNA with non-identical homologous chromatids during crossing over, resulting in homologs made up of non-identical sister chromatids. Crossing over happens in prophase I; therefore, all subsequent stages feature non-identical sister chromatids.
