Question

Scientists have studied a fruit fly, Drosophila, to better understand early embryonic development and have discovered that the cell cycle changes as embryonic development proceeds Model A represents the first 13 cell cycles after fertilization, which only includes two phases. Model B represents cell cycles 14 through 16, which are more complex and include a G2 phase.
What of the following explains the advantage of a G2 phase during embryonic development?

A Cells can undergo the cell cycle more quickly with a G2 phase.
B Cells can replicate more DNA with a G2 phase.
C Cells are checked for DNA damage before entering mitosis with a G2 phase
D Cells are able to produce two new daughter cells with a G2 phase.​
