Answer:
A. Blood is responsible for helping us digest food.
Explanation:
First off, imagine what that'd be like if you get a cut and your blood had digested food in it. Gross. But seriously, the other three options are true facts. What does help us to digest food, is bacteria, and other parts of the digestive system.

Hope that helps and have a great day!
