Based on the wording of your question, I believe the answer is C because from any parent function that is similar to A, B, or D, which can be interchangeable, you cannot make an Absolute | | from these types of equations, and you cannot remove an absolute by squaring it, adding to it, and so on. Therefore, C is the only function that differs from the other options and cannot have a relationship to the parent function. If you meant something else by this question please clarify.
