Viscosity 

It is the internal resistance of a liquid to flow which exists due to the relative motion between two layers. It decreases with increase of temperature. It is calculated as the force per unit area needed to maintain a velocity difference of unity between two parallel layers of liquid unit distance apart.

As we learnt in Viscosity - Viscosity of liquids decreases as the temperature rises.

\mathrm{Viscosity\: of\: liquid\: \: \alpha\: \: \frac{1}{temperature}}
Therefore, Option (2) is correct
