చాకలి, రోకలి, వాకలి, ఆకలి.
Explanation
This riddle answers 'teeth' (చాకలి means teeth). The wordplay uses similar-sounding words (చాక, రోక, వాక, ఆక) to describe teeth's characteristics: they bite/chew, obstruct/block food entry, speak/talk, and satisfy hunger—making the riddle cleverly highlight the multiple roles teeth play in eating, speaking, and survival.
