According to Signal Detection Theory, when a person is unsure about a stimulus, they tend to respond by indicating that they have detected the stimulus. In the context of this experiment, this means that the participant will likely respond by indicating that they have detected an emotional expression, even when the image is blurry and hard to distinguish.

In this scenario, there are two possible outcomes:

1) The participant detects an emotional expression correctly (hit)
2) The participant indicates they have detected an emotional expression, even though there is none (false alarm)

Therefore, the participant is most likely to have hits and false alarms as their outcomes, which corresponds to choice C.
