Answer:

Option A is correct

Undefined

Step-by-step explanation:

Given that:

[tex]x^2=-169[/tex]

Taking square root both sides we have;

[tex]\sqrt{x^2}=\sqrt{-169}[/tex]

⇒[tex]x = \pm \sqrt{-169}[/tex]

There are no real solution but rather than there are two complex number i,e 13i, -13 i

Therefore, the value of x are undefined.
