The answer is letter C and E.

For A and B, they look like a linear transformation, however when you add the constants, it will not zero out. For letter D, it is not a linear transformation because of the scalar multiplication. The value given in D is an absolute value, so whether or not you multiply this, it will not result to the same number.
