Answer:
Option C is correct
value is equivalent to |f(i)|
Explanation:
Modulus of the complex number z = a+ib is given by:

As per the statement:
Given the function:

Substitute x = i we have;
; where, i is the imaginary part.
We have to find |f(i)|.

By definition of modulus;

⇒

⇒

Therefore, the value of |f(i)| is,
