The correct answer is D. A maniac state
Step-by-step explanation:
A maniac state or episode occurs in individuals with bipolar disorder and other types of mental disorders and involve periods of time of few days or even weeks in which the individual experiences increased optimism or euphoria which makes it more talkative, feeling more confident than normal, trying to do unusual activities or achieve irrational goals and sleeping less. This kind of episodes might represent a risk for the individual because in some cases they lead to irrational actions.
This is the type of episode or state Tess is experiencing because she is hyperactive and more talkative. But besides this, she plans to fly solo across the Pacific Ocean which is an irrational goal and she is sleeping less. All of these behaviors and features are part of a manic state, which also implies Tess might have a bipolar disorder.
