The complex number is 4 - 7i. The 2nd option is the answer.

How to find the complex number?

A complex number is a combination of real values and imaginary values. It is represented by z = a + ib,

where a is the real part and ib is the imaginary part

Given that: real = 4 and imaginary = -7i

Since the form of a complex number is z = a + ib. Thus, a = 4 and b =  -7i. Therefore, the complex number will be:

z = 4 + (-7i)

z = 4 - 7i
