Hint: To answer this question we have to know about viscosity. Viscosity generally works in liquid. In liquid the force of attraction between the particles of liquid generally causes viscosity.
Complete Step by Step Solution:
Viscosity of a liquid is defined as its power to resist it from flowing. It occurs due to the intermolecular force of attraction between the molecules of liquid and the molecules of the liquid and the surface of the solid.
If we increase the temperature of the liquid its thermal energy will increase which decreases the strength of intermolecular force of attraction in liquid molecules. Due to decrease in intermolecular force of attraction the liquid molecules will be free to move and flow with high speed and viscosity decreases.
As the density of the liquid increases the intermolecular force of attraction also increases so viscosity also increases. Thus viscosity for denser liquid will be more than less denser liquid. For example oil has more viscosity than water.
The viscosity of the solvent depends on the density of the liquid.
Thus the correct option is D.
Note: Viscosity depends on temperature, pressure and density of liquid. More denser liquid will cause more viscosity in liquid. For example, syrup is denser than water, so it is more viscous liquid than water.
