c ) all answers are possible
DNA replication machinery begin to assemble at origin of replication.
G1 cyclin - CDK complexes inactivates cdh1
G1 cyclin -CDK complex activate S phase cyclin - CDK expression
S phase cyclin / CDK activate preplication complex that began to assemble in step 1.S phase and G2 phase happen.
