Mercury has a higher dynamic viscosity than water. Water's dynamic viscosity at 20°C is 1.005 centipoise. Mercury's dynamic viscosity at 20°C is 1.6 centipoise.
Hence dynamic viscosity of water in comparison to mercury is lower.
Hence dynamic viscosity of water in comparison to mercury is lower.

The answer is wrong.
The Viscosity of water is less than mercury. Viscosity of mercury is 1.6 times the water viscosity.

Shear stress develop in water is more than mercury. As viscosity is directly proportional to shear stress.
So water has higher viscous property than Hg.
So water has higher viscous property than Hg.

Dynamic viscosity of mercury is higher than that of water but a kinematic viscosity of mercury is lower than water because of their density.
Value of dynamic and kinematic viscosity of water is 1*10^-3 and 1*10^-6 but of mercury 1. 56*10^-3 and 1. 15*10^-7 in Ns/m^2 and m^2/s.

The kinematic viscosity is the dynamic viscosity divided by the density.
Mercury is a lot denser than water, so its kinematic viscosity is lower than the kinematic viscosity of water. But that's just because mercury is very dense. But The dynamic viscosity of mercury is greater than water.
