उत्तर
Grease
Explanation:
Viscosity is the measure of a fluid's resistance to flow. The thicker or more resistant a liquid is to flow, the higher its viscosity.
- Water has the least viscosity.
- Coconut oil and ghee have higher viscosity than water but less than grease.
- Grease is thick and flows very slowly, hence it has the highest viscosity.
