Although you can check the units of all the four options, it will be wise to note that option (B) and (C) can never have the same units. So if you check just the two options you will see that dynamic viscosity has the unit of Pa-s.

Explanation:
Dynamic viscosity is the property of a fluid that determines the resistance to shear stress. It is also known as absolute viscosity. It is measured in units of Pascal seconds (Pa.s) or Poise (P). The unit of dynamic viscosity is not m2/s.

Different properties and their units are as follows:

- Thermal diffusivity: m2/s
- Kinematic viscosity: m2/s
- Dynamic viscosity: Pa.s or P
- Mass diffusivity: m2/s

Therefore, the correct answer is option C, dynamic viscosity, as its unit is not m2/s.
