Who does a producer submit a QC Program to?

The correct choice indicates that a producer submits a QC Program to either a State Materials Office (SMO) or a District Materials Office (DMO). This is essential because these offices are responsible for overseeing the quality control processes for materials used in construction projects across the state.

The SMO and DMO serve as regulatory bodies that ensure compliance with the Florida Department of Transportation's standards and guidelines. By submitting the QC Program to them, producers demonstrate that they are following the established protocols for quality assurance and control, which is crucial for maintaining the overall integrity and safety of transportation infrastructure.

The other options might involve various levels of government, boards, or acceptance processes, but they do not specifically pertain to where a producer would submit a QC Program for formal oversight and approval in relation to materials quality for construction projects. Thus, the focus on the SMO or DMO accurately reflects the proper chain of submission in the context of FDOT regulations.
