Final answer:
The insurance company retains ultimate control over the Owners & Contractors Protective Liability policy.
Step-by-step explanation:
The ultimate control over the Owners & Contractors Protective Liability policy lies with the insurance company. They are responsible for issuing and managing the policy.
In this scenario, DEC Construction hires Mac Electric as a subcontractor and requires them to have this insurance policy. However, the control over the policy remains with the insurance company.
DEC Construction may set the requirement for subcontractors to have the insurance, but they do not retain ultimate control over the policy.
