Here is your answer:
The answer is option B "a table that lists the quantity of a good all consumers in a market will buy at each different price." So let's just say you want to buy a blue name-brand backpack at a store at this store it's 20:95, and at a another store it's 25.95 you decided to find a way to save money so you made a table on how much each of the book bags cost which would be a market demand schedule.
Hope this helps!
