Papal infallibility

All right.

Question 12: Papal infallibility means, A, the Pope is preserved by the Holy Spirit from committing mortal sins; B, anything the Pope teaches is guaranteed by the Holy Spirit to be true; C, the Pope's teachings must be obeyed because he is under the guidance of the Holy Spirit and thus speaks for the Holy Spirit, who cannot err; D, the Pope is incapable of teaching erroneously on matters of faith and morals when he teaches publicly and officially a doctrine for all Christians, not just Catholics, to hold.

D, right, from the C to D there?

Yeah, I think it's gonna be D 'cause it's like a negative protection.
