Shawna's conservative decision criterion means that she will only respond "Yes" when she is very sure about the presence of the stimulus. This will result in fewer false alarms (i.e. saying "Yes" when there is no stimulus) but a higher number of misses (i.e. failing to say "Yes" when the stimulus is present) since she has set a high threshold for detecting the stimulus. Therefore, option D is the best choice.
