Chi Squared Test Definition

My question asks to choose the statement that is not true about the chi squared test.

A.The chi squared test should be performed only on categorical data.
B. The lower the degrees of freedom, the more skewed to the right the chi-squared distribution will be.
C. The shape of the chi squared distribution depends on the degrees of freedom.
D. Values for the chi squared statistic can be negative, positive or zero.
By looking through the web definition, I felt that B. and D. contain some truth, but my book fails to mention B.'s content. I didn't find much info on A. nor C., but was contemplating choosing C. Anyone have some suggestions?
