What significant event occurs in the "Conversion of Saul"?

The significant event in the "Conversion of Saul" is indeed that Saul is blinded and later baptized. This moment is pivotal in biblical narratives, specifically in the New Testament, where Saul, a fervent persecutor of Christians, experiences a dramatic transformation. While traveling to Damascus to arrest Christians, he is struck by a bright light from heaven, causing him to lose his sight. After this experience, he is taken to Damascus, where he spends three days blind until Ananias, a Christian disciple, is guided by God to lay hands on him, restoring his sight and subsequently baptizing him. This event marks the turning point for Saul, who later becomes known as Paul the Apostle and a key figure in the spread of Christianity.

The other options do not align with the events described in this narrative. There is no account of Saul being crowned king, becoming a merchant, or building a new city during this particular episode; instead, it focuses on his transformative encounter with the divine and the beginning of his mission as a proponent of Christianity.
