Effervesce means to bubble up or fizz, and can also describe someone who is lively and full of energy. The best match is the same word itself, since it conveys both the literal sense (to fizz) and the figurative sense (to be lively or enthusiastic). The other options describe different ideas: extricate means to free from difficulty or entanglement; jaundice refers to a medical condition (yellowing of the skin) or a bitter mood; languor means a lack of energy or vitality. So the word that fits closest is effervesce because it directly shares the same meaning.
