Even though conductor has free electrons, current doesn't flow if it is open circuit. So the answer is "False".

If there is no free electrons.

Free electrons are support to moving current. We know current formula, any in conductor free flow of electrons is called current. It is true.

That is not possible because of potential difference is not presents.

Yes free electrons makes the possibility of flow of electric current because flow of these free electrons causes flow of current. But for this purpose an electric pressure is required. i.e., Known as voltage.

Current can only flow if potential difference is applied through a material having free electrons. So only presence of free electrons does not make sense.

If there is no potential difference how can we got the current, So only free electron could not make current.

We can get free electrons in conductors which makes the current to flow through it.
