The correct option is D. when there is continuous movement but no change
Explanation:
In chemistry, dynamic equilibrium can be described as a condition in which the number of reactants being converted into products is equal to the number of products being converted into the reactant. It means that the rate of forward reactions becomes equal to the rate of reverse reaction. Dynamic equilibrium is a balance between continuous processes.
A dynamic equilibrium will be reached in the process of diffusion when molecules will move in and out from a system at a continuous rate.
Water itself does not live. Water does not need sustenance of any sort to continue to function and it does not pass on any sort of DNA to any build a future generation so it is not biotic.
