Solution

Answer: (c) Decrease

With the increase in temperature, the kinetic energy of the molecules of liquid increases which can overcome the intermolecular forces. Hence, the liquid starts flowing.

In other words, the viscosity of a liquid decreases with increase in temperature. It has been found that the decreases are about $2 %$ per degree rise in temperature.
