When sufficient heat is applied, double-stranded DNA denatures into two single-stranded molecules as the heat breaks all of the hydrogen bonds. In an experiment, molecules of single-stranded DNA from species X are separately hybridized with putatively homologous single-stranded DNA molecules from five species (A-E). The hybridized DNAs are then heated, and the temperature at which complete denaturation occurs is recorded. Based on the data below, which species is probably most closely related to species X?

Following statements are regarding to the protein phosphatase Cdc14 function in budding yeast.
A. In budding yeast, the protein phosphatase Cdc14 throws the switch between two mutually antagonistic states during anaphase.
B. Cdc14 is kept inactive during most of the cell cycle, but is activated during anaphase by a GTPase signaling pathway known as the mitotic exit network.
C. Mitotic exit network is unresponsive to spindle position and becomes active in anaphase.
D. Cdc14 phosphatase activated by the activation of protein kinase cascade.
E. Cdc14 dephosphorylates APC/CCdh1 and Sic1 to promote mitotic cyclin degradation
and mitotic CDK inactivation, respectively. This process leads to exit from mitosis.
