What is a characteristic of a person described as 'ebullient'?

The term 'ebullient' is used to describe a person who is full of energy, enthusiasm, and excitement. When someone is characterized as ebullient, it typically means they express their positive feelings and lively spirit openly and exuberantly. This joyfully energetic disposition can be seen in their animated behavior, cheerful demeanor, and readiness to engage with others in a vibrant manner.

In contrast, the other choices depict traits that do not align with the essence of being ebullient. A contemplative person tends to be more thoughtful and pensive, reserved individuals are characterized by their tendency to keep feelings to themselves and not show much outward emotion, while an indifferent person shows a lack of interest or concern. None of these characteristics reflect the lively and spirited nature implied by 'ebullient.'
