The correct option is C Anaphase
The shortest phase in mitosis is anaphase. During anaphase, the sister chromatids separate and move to opposite poles.
The longest phase in mitosis is prophase. During prophase, chromatin undergoes condensation and compact chromosomes are visible in the cell. The nuclear envelope and nucleolus disappears by the end of prophase.
Prophase lasts for 30 to 60 minutes; metaphase lasts for 2 to 10 minutes; anaphase lasts for 2 to 3 minutes and telophase lasts for 3 to 12 minutes.
