【評論內容】The sentence is using a participle phrase to provide additional information about the subject "he" (someone). The phrase "discouraged by the lack of interest in his proposal" modifies the subject and tells us the reason for his action in the main clause. The correct participle form is "discouraged." The other options do not fit the context or the tense of the sentence.
