If z = a-bi, the complex conjugate of z is a + bi.

So the imaginary part is "b"

"b" is opposite of - b, so correct answer is c)

If z = a - bi, which of the following must be true of the imaginary part of the complex conjugate of z?a. It must be the opposite of - bi.b. It must be the opposite of bi.c. It must be the opposite of - b.d. It must be the opposite of b
