Solution

The correct option is C Imaginary numbers
You know, $i = \sqrt{- 1}$ which represents an imaginary number.
So, the number $5 + \sqrt{17} i$ will be an imaginary number because the part $\sqrt{17} i$ contains the letter "i" which denotes an imaginary number.
∴ $5 + \sqrt{17} i$ is an imaginary number.
