This is the hint .

Now question is very straightforward .

We can see penguin only in Antarctica that is south pole.

We can see polar bears only in arctic region that is north pole .

So , in their natural habitat , penguin will not be seen with polar bears .

But in a zoo , we can see them together !!!
