Answer:
<u>Option C.</u>

To determine if a line represents a valid function, we may use the vertical line test.
If it is touching more than one point on the line at a time, the line is not a valid function.
So, according to the previous rule, the function of figure C is a function and its inverse is also a function.
<u>The answer is option C.</u>
