Final answer:
Jesus was sought by His mother and brothers while teaching the multitudes, as recorded in the Gospels. This was distinct from His interactions with the Pharisees, His disciples who were fishermen, or the Roman soldiers.
Step-by-step explanation:
The individual who came to speak to Jesus in the context of the Gospels while he was addressing the multitudes was B: His mother and brothers. This instance is mentioned in the Gospels, where Jesus is teaching the crowd and is told that His mother and brothers are seeking to speak with Him. Jesus uses this moment to teach about the spiritual family, indicating that those who do the will of His Father are His true family. While the Pharisees did interact with Jesus on many occasions, questioning and challenging him, the specific scenario described in the question involves His family members. The fishermen, such as Peter, were already His disciples by this time, and the Roman soldiers had encounters with Jesus, but not typically in the context of coming to Him during His teachings to the crowds.
Through the Gospels, Jesus's interactions with various groups - Pharisees, tax collectors, sinners, and His disciples - are narrated to depict His teachings and the responses He received from different sectors of the society at that time, notably within the context of Roman-occupied Palestine and the expectations of Jewish society.
