Answer:
B. He means he is a Baptist missionary.
Step-by-step explanation:
It is most likely that Pratt means he is a Baptist missionary when he says "I am a Baptist." A Baptist is a member of a Christian denomination that follows the principles of Baptist churches, which include a belief in the autonomy of the individual church and the priesthood of all believers. Missionaries are people who are sent by a religious organization to spread their faith and teachings to people in other countries or regions. Therefore, "I am a Baptist" could be interpreted as "I am a member of the Baptist faith and have been sent on a mission to spread its teachings."
