A dominant strategy is one that results in the best outcome for a player, no matter what the other player does. In this case, regardless of whether Alice confesses or doesn't confess, Bob's best outcome (smallest prison sentence) comes from confessing. If Alice confesses, Bob gets 8 years for not confessing and 5 years for confessing. If Alice doesn't confess, Bob gets 10 years for not confessing and 1 year for confessing.
