Use the Data in the Accompanying Table to Answer the Question

Use the data in the accompanying table to answer the question.
Minutes Spent in Cell Cycle Phases
$$\begin{array} { | l | l | l | l | l | } \hline \text { Cell Type } & \mathbf { G } _ { \mathbf { 1 } } & \mathbf { s } & \mathbf { G } _ { 2 } & \mathbf { M } \\\hline \text { Beta } & 18 & 24 & 12 & 16 \\\hline \text { Delta } & 100 & 1 & 0 & 0 \\\hline \text { Gamma } & 18 & 48 & 14 & 20 \\\hline\end{array}$$
The data in the table were obtained from a study of the length of time spent in each phase of the cell cycle by cells of three eukaryotic organisms designated beta, delta, and gamma.
Which of the statements is the best explanation for the difference between time spent in S phase by beta and gamma?

A) Gamma contains more DNA than beta.
B) Beta and gamma contain the same amount of DNA.
C) Beta cells reproduce by binary fission and gamma cells reproduce by mitosis and cytokinesis.
D) Beta is a plant cell and gamma is an animal cell.
