Answer:
C - He is not afraid to challenge the group
Explanation:
(A) We know that he isn't pretending to agree with the group because that just wouldn't make sense since they are accusing him of being an alien.
(B)We know that he isn't frightened because it says that he stands there defiantly which is kind of like he is confident. The stage directions also don't show any sign of him being afraid of the group.
(C)If he is standing there defiantly, he is confident and unafraid to challenge the group because if you read the whole story/teleplay, you would know that Steve isn't an alien which means he would have nothing to hide. Therefore, there is no reason for him to be scared to challenge the group.
(D)If you read the whole story/teleplay you would know that Steve isn't an alien so number 4 wouldn't make sense because the group can't "know the truth" if there is no secret/truth.
