Answer:
The correct answer is option C. At parties, Jed liked to sing funny songs in a goofy, high voice.
Step-by-step explanation:
As we know, Jed is a character in a short story. We must find the sentence that does not fit with the others.
From what we read in most sentences, Jed is a shy person who hardly ever talks and spends his time alone.
However, sentence C says Jed at parties liked to sing funny songs in a goofy, high voice. This is definitely not a feature of someone with Jed's description.
That is why we can say that the correct answer is option C.
