I think option D is correct because with increasing temperature viscosity for gases increases with increasing temperature and viscosity for liquids decrease with increasing temperature.

Because in liquid shear, stress is mainly due to the cohesive force which predominates the molecular momentum transfer hence increase in temp leads to a decrease in the cohesive force of attractions in liquids so viscosity decreases.
