Not always, because with evidence it can also be wrong. You need at least two to make a point if necessary.
Answer:
You didn't mention what the question is about, but I'm going to guess it's not D or B. So it's either A or C.
A. says something like when someone is sleep deprived, they are so tired and out of it that they might confess to committing the crime. C. says something like when the suspect is sleep deprived, they are unable to understand what they are saying, therefore they could confess to a crime they didn't commit.
I'll take an educated guess and say it's
C. Sleep deprivation can cause distress in the body and mind, which makes suspects unable to understand what they are saying or the consequences of their confession.
Resolution
The resolution of the story is the end. All of the conflicts are solved and subplots are wrapped up. Tension usually builds as the conflict begins and becomes more complicated. The author does this through the sequence of events, language, conflict, sentence structure, tone, and mood. The resolution is not an area of tension in a story. If there is, usually it's so that there can be a sequel.
