Answer:
B. The decision has consequences that matter a lot to the character.
Step-by-step explanation:
Unlike the other three options, option B demonstrates stakes that are put into place for the character. Why should we care if there's no serious risks, if it's not surprising? Building tension is all about suspense and the unknown; and if things that matter a whole lot for the character are on the line, the tension is strong and we're on the edge of our seats.
