Option C - All real numbers                                      

Step-by-step explanation:

Given : Function

To find : The domain of given function ?

Solution :

Domain is defined as the set of values for which function is defined.

We have given the function,

We know, for any value of the function   is defined.

Which means the set of all real numbers defined the given function i.e.

Therefore, Option C is correct.

The domain of   is all real numbers.
