I'd go with A or C. Definitely not B or D.
Answer:
The possessive error is up
B. Do. B is the correct word for this sentence because are the others are grammatically incorrect
I believe it's persuade. You want to persuade schools to offer better food. B is wrong because you are not entertaining anyone. Inform is wrong because you would just be stating facts. A is wrong because you are not telling someone to do something. Hope this helps! ;)
D- Barked
