I have been asked this question in final exam.

Question is from Flow Behaviour Models in division Rheology of Dairy Engineering

Correct option is C. Static and dynamic

Best explanation: The deformation forces which act on a solid body or a liquid can be Static: the force is acting constantly and its direction and magnitude are constant and dynamic: the magnitude and/or direction of the force(s) are variable as a function of time.
