In the book of Acts, what was the main reason for the conflict between Paul and the Judaizers regarding Gentile converts?

A The Judaizers were jealous of Paul's success in converting Gentiles. B The Judaizers believed that Gentile converts needed to adhere to Mosaic Law, including circumcision, for salvation, while Paul emphasized salvation through faith in Jesus Christ alone. C Paul wanted to create a separate church for Gentile believers. D The Judaizers were sent by the Roman government to undermine the early church.
