Solution

The correct option is C
Cyclin-CDK Complex

The complex formed by the various interactions of cyclins and CDKs - Cyclin CDK complex is responsible for the regulation and progression of the cell cycle. Cyclins and CDKs on their own cannot arrest or aid in the progress of the cell cycle. Phosphorylated CDK is usually an internal cell-signal that aims to label a used CDK protein for degradation.
