Which stage converts to breathing air and crawls onto land?

Explanation:
In frogs, life starts in water as eggs that hatch into tadpoles. Tadpoles live underwater with gills and no legs. Through metamorphosis, they develop legs and lungs, enabling them to breathe air and move onto land. That intermediate, air-breathing, land-dwelling stage is the froglet. Eggs can’t breathe air or crawl onto land, tadpoles are still fully aquatic, and adult frogs have completed the transition, so the froglet best fits the description of converting to breathing air and crawling onto land.
