Harry is facing an important test and expects to do poorly. he is so anxious that he cannot concentrate or study effectively, but he figures that since he's going to do badly anyway, he should not bother preparing. this is an indication of harry's question 3 options: social reality. social comparison. self-concept. self-esteem.

The answer is self-esteem. Without thinking of any solution, Harry already marked that he would fail even if tries to prepare himself. He already set his mind that he would have poor results. 

The other options are incorrect since social reality is irrelevant to his condition because he didn't even try to make an effort. Social comparison is also not the answer because he was not comparing his performance with others. Lastly, self-concept was not the answer because it all came from having a low self-esteem of himself.
