Accepted Answer

A)   It is always a negative number, although it is sometimes reported as an absolute value.
B)   It is sometimes a negative number and sometimes a positive number, depending on the magnitude of response.
C)   It is always a positive number because price and quantity are directly related in terms of demand.
D)   It can be a positive number or a negative number, but is always reported as an absolute value.
