Concept:The words came from the angel who appeared to Cornelius before his baptism into the Christian faith.
Explanation:Cornelius was a Roman centurion in Caesarea, described as a devout man who feared God and gave alms generously.
While he was praying, an angel of God appeared to him and made the statement about his prayers and alms rising as a memorial before God.
The angel told him to send messengers to Joppa for Simon Peter, who would explain the way of salvation to him.
Peter came and preached Jesus to Cornelius, his family, and his close friends.
During Peter's message, the Holy Spirit came down on all those who heard the word, and they were baptized in the name of Jesus Christ.
This shows that the statement marked the moment leading to Cornelius' conversion and his reception into the church.
Thus, the person whose conversion was marked by the angel's declaration is Cornelius.
Answer:B. Cornelius
