B) one; ceteris paribus
C) two; ceteris paribus
D) three; marginal benefit

To graph a relationship among several variables, we need to hold two variables constant and use the assumption of ceteris paribus. This allows us to isolate the relationship between the two variables we are interested in. Holding all but one variable constant (option A) would not allow us to examine the relationship among several variables. Holding three variables constant (option D) would be too difficult and inefficient, and marginal benefit is not relevant to this concept.
