According to the first council at Jerusalem, which of the following was not binding on a Christian?

According to the first council at Jerusalem, it was not binding on a Christian to pray five times daily in the temple. The council, as recorded in the book of Acts in the Bible, discussed several issues, including the question of whether Gentile converts to Christianity should be required to follow Jewish customs such as circumcision and following dietary laws. The council concluded that Gentiles did not need to follow these customs but should instead abstain from eating meat that had been sacrificed to idols, from consuming blood or meat from strangled animals, and from sexual immorality. The council did not address the issue of praying five times daily in the temple, as this was not a requirement for Christians.
