Final answer:
The answer is A) One new humanity, reflecting the early Christian belief that Jesus's death and resurrection opened the way for all people to receive salvation without regard for social or cultural divisions.
Step-by-step explanation:
Paul emphasizes that Christ has eliminated ALL cultural, religious, socioeconomic, and racial barriers and made A) One new humanity. This notion signifies the early Christian idea that Jesus's death and resurrection provided salvation to all, regardless of background, challenging the Roman system of social hierarchy and offering universal reconciliation.
