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.

The tracheal (respiratory) system in Drosophila embryos develops from epithelial sacs. The approximately 80 cells in each of these sacs become reorganized into primary, secondary, and tertiary branches without any cell division or cell death. This reorganization is initiated when nearby cells secrete a protein called Branchless, which acts as a:
