Which word best describes a person who is described as "ebullient"?

"Ebullient" refers to a person who is overflowing with enthusiasm, energy, and excitement. When someone is described as ebullient, they display a lively and animated demeanor, often expressing their happiness or enthusiasm very openly. Therefore, the word that best captures the essence of an ebullient personality is "exhilarated and enthusiastic," as both terms reflect a high level of spiritedness and joy.

In contrast, the other options depict states that are opposite or contrary to ebullience. Depressed and melancholic suggest sadness or gloom, which runs counter to the vibrancy associated with ebullience. Quiet and reserved imply a more subdued and restrained attitude, lacking the lively expression characteristic of an ebullient person. Lastly, indifferent and apathetic denote a lack of interest or concern, which starkly contrasts with the passionate enthusiasm that ebullient individuals typically exhibit.
