Answer 1

See below

Explanation:

Complex Number is a number that consists both real part and imaginary part. It can be generally written in equation as
`\displaystyle{z=a+bi}` where
`\displaystyle{a}` is real part while
`\displaystyle{b}` is imaginary part.

Since complex number consists two parts - real and imaginary, we can say that all real numbers and imaginary numbers are indeed complex number.
