The correct answer is: B. discouraged
To be discouraged is to lose confidence or hope. When the editor refused to publish your first article, you were probably feeling discouraged because you had put a lot of work into it and you were hoping that it would be published. You may have felt like your work was not good enough or that you were not good enough to be a writer.
The other options are not as accurate descriptions of how you might have felt. To be displeased is to be slightly annoyed or unhappy. To be dissatisfied is to be not completely satisfied. To be disturbed is to be upset or agitated.
It is important to note that these are just general descriptions of how you might have felt. Everyone experiences emotions differently, and your specific feelings may have been different from the feelings described above.
