The prophet Joel speaks of 'pouring out of the Spirit on all people.' How does Peter, in Acts 2, interpret this prophecy in relation to the events of Pentecost?

A He sees it as a partial fulfillment, indicating the beginning of the age of the Spirit, open to all who believe. B He dismisses it as irrelevant to the current events, focusing instead on the resurrection of Jesus. C He interprets it as a complete and final fulfillment, signifying the end of the need for prophets. D He believes it only applies to the Jewish people present in Jerusalem at that time.
