Answer:
c. Papaya
Explanation:
Papain is an enzyme commonly found in pulp and especially in papaya milk, found in green papaya peel. This milk is very rich in papain, so it can be used to tenderize meat.
So get a green papaya, and remove the milk from the peel. That done, just add it to the meat, and let it work for about three hours. Don't forget to remove the milk at the end of time.
