Final answer:
The MPPDA, under the Hays Office, enforced guidelines by forcing studios to pay hefty costs if their films did not receive a seal of approval, with Joseph Breen being key in this enforcement. This approach maintained Hollywood's adherence to the Production Code, separate from the MPAA rating system that came later.
The correct option is B. Forced studios to pay hefty costs if their films did not receive a seal of approval; Joseph Breen
Step-by-step explanation:
The MPPDA, also known as the Hays Office, enforced guidelines in Hollywood primarily through the implementation of the Production Code, commonly known as the Hays Code. Joseph Breen is the individual who notably enforced the Production Code.
To ensure compliance with the code, the Hays Office under Breen would review films before their release. If a film did not adhere to the Production Code, it would not receive the Hays Office Seal of Approval, and without this seal, the film would typically struggle to be distributed or shown in theaters, effectively constituting a hefty financial penalty to the studio.
This system was distinct from the later establishment of a rating system by the Motion Picture Association of America (MPAA), which classified films by content suitable for various audiences and is still in use today. Joseph Breen's enforcement of the Production Code played a pivotal role in regulating Hollywood's film content until the Code's influence waned in the 1960s, eventually being replaced by the modern MPAA rating system.
The correct option for how the MPPDA enforced guidelines is B) Forced studios to pay hefty costs if their films did not receive a seal of approval; Joseph Breen.
