Multiple Choice

Suppose we are given that the value of a particular utility function is a constant.That is,U(X,Y) = c.Then,the total derivative of this relation is:

• A) (  U/  X)dX + (  U/  Y)dY = c.
• B) (  U/  X)dX + (  U/  Y)dY = 0.
• C) (  Y/  X)dX + (  X/  Y)dY = 0.
• D) (  Y/  X)dU + (  X/  Y)dU = c.
