Explanation

After the death of Stephen, who was one of the seven deacons chosen to distribute food to the poor and widows, there was a great persecution of the believers in Jerusalem. The believers, except for the apostles, were scattered throughout Judea and Samaria. Therefore, the only group of believers not scattered by the great persecution was the apostles. The apostles were the twelve men chosen by Jesus to be his closest followers and to continue his teachings after his death and resurrection. They were the ones who were commissioned to spread the gospel to all nations. In contrast, the deacons were chosen to assist with the distribution of food and other administrative tasks within the church. Prophets were individuals who were inspired by God to deliver messages to the people, and disciples were followers of Jesus who learned from his teachings. Therefore, the correct option for this question is option B: apostles.
