Which of the following best characterizes someone who is 'effervescent'?

The term 'effervescent' is often used to describe someone who is lively, enthusiastic, and full of energy, reminiscent of the bubbles in a carbonated drink. This word conveys a sense of joyfulness and vivacity, suggesting that the individual has a bubbly personality that is both engaging and cheerful. An effervescent person tends to radiate positivity and often draws others in with their spirited demeanor.

In contrast, the descriptions of someone who is quiet and reserved, calm and composed, or stern and serious align with more subdued or serious temperaments, which do not capture the vibrant essence of an effervescent person. Rather than being characterized by energy and enthusiasm, those attributes suggest a lack of the dynamic personality associated with effervescence.
