Causes that deactivates M phase cyclin/CDK complexes, which triggers exit from mitosis is
D. Phosphorylation of Sic1.
Phosphorylation of sic1 occurs when it is inhibited by M-CDK during mitosis and this M-CDK also inhibits gene regulatory protein required for production of Sic1. Sic1 and M-CDK mutually inhibit each other.
