    Solution:

     Ethylene glycol of the following is expected to have a maximum viscosity at a given temperature.

    Glycol has maximum viscosity because it has two −OH groups and there is greater intermolecular H−bonding in comparison to water and methanol. Kerosene is a mixture of hydrocarbons.

    Hence option C is correct.
