Correct Answer - Option 1 : dilatant fluid

Explanation:

Thixotropic Fluid: 

Fluids for which dynamic viscosity decreases with the time are termed as thixotropic fluids.

Example- Lipstick, Crude Oil, etc.

Pseudoplastic Fluid:

Non-Newtonian fluid for which dynamic viscosity decreases with an increase in the shear stress is termed as pseudoplastic fluid. 

Example- Blood, Paints, etc.

Dilatant Fluid:

Non-Newtonian fluid for which dynamic viscosity increases with an increase in the shear stress is termed as dilatant fluid.

Example-  Sugar suspension, Starch suspension, etc.

Rheopectic Fluid:

Fluids for which dynamic viscosity increases with the time are termed as rheopectic fluids.

Example- Gypsum, Bentonite solutions etc.
