Choose the answer that correctly explains the geometric representation ofmultiplying a complex number by -1+i.
A. -1 + i has a modulus of 2 and an argument of 45°, so multiplying a complex number by -1 + i will dilate the complex number by a scale factor of 2 and rotate it 45° counterclockwise.
B. -1 + i has a modulus of V2 and an argument of 135°, so multiplying a complex number by –1 + i will dilate it by a scale factor of V2 and rotate it 135º counterclockwise.
C. Multiplying a complex number by -1 + i will rotate it 180°, but there will be no dilation
D. Multiplying a complex number by –1 + i will rotate it 180° and translate it square root of 2 units to the right
