"Demand Schedule" is some type of table in the economics , I believe
. So, A chart showing the impact of demographic changes on demand (option A.) would not be your answer; a graph tracking the increase in the demand at decreasing. prices (option C.) wouldn't be your answer ; A report analyzing factors causing a change in demand for good (option D. ) would not be your answer
So, most likely your answer would be: "a table showing the the quantity demanded for a good at different prices " (option B.)
Good Luck!
