It is a thin film.

The Correct answer is A.

It's a thick film because metal to metal contact is avoided at high speed.

The condition for thin film is that metal to metal contact is not avoided even at high speed.

Hydrodynamic and hydrostatic both are come under thick film lubricant but hydrodynamic film is duo to relative motion and hydrostatic films is due external pressurized pump.
