"Plaintive" is an adjective that means "sounding sad and mournful." So, we need to pick out an adjective that means something similar to "sad" or "mournful." So, "celebratory" cannot be the correct answer because it is an antonym of "sad" and "mournful." "Sorrowful," however, is an adjective that means either "feeling or showing grief" or "causing grief," and because it is the answer choice closest in meaning to "plaintive," "sorrowful" is the correct answer.

None of the other answer choices are close in meaning to "reluctant": “cantankerous” means grumpy; “enthused” means excited; “demonic” means marked by qualities of the devil or of demons; “susceptible” means vulnerable or in danger from something specific.

If you are “furious,” you are very angry. Something that is “humorous” is very funny. If you are “jealous,” it means you want something that someone else has.

"Surly" means sullen, uncivil, and unsmiling, so "sulky," an adjective that means brooding, petulant, and in a bad mood, is the correct answer.
