B. Exhausted
The tone is very exasperated, to the point to where for example if you had been doing school work all day, only to find out you had to walk home which was about 7 miles from your school, you would feel as the speaker in this.
Hope this helped!!! (:
Scott was a heap of flowing, heartbroken tears for a long time after his beloved puppy passed away.
Note: Be careful with your tense. At the beginning, you said 'was sad' (past tense), and at the end, you put 'puppy dies' (present tense).
Hope this helps!
