Consider the given function is 

If  , then
, then  is an even function.
 is an even function.
If  , then
, then  is an odd function.
 is an odd function.
Now, substitute x=-x in the given function.

To check whether the given function is odd, we have to determine whether  is equivalent to
 is equivalent to  .
.
Therefore, the correct option is C.
