The bag is more concentrated in starch than the beaker. This is because the bag contains a solution of starch and water, while the beaker contains only water.
The starch molecules are unable to pass through the plastic bag, so they remain concentrated in the bag. The water molecules, however, are able to pass through the bag, so they diffuse into the beaker, making the solution in the beaker less concentrated in starch.
If you were to leave the bag and beaker for a long enough period of time, all of the starch molecules would eventually diffuse into the beaker, and the concentration of starch in both the bag and beaker would be the same. However, in practice, this would take a very long time, as the rate of diffusion is relatively slow.

Answer: A. an inhibitor
An enzyme inhibitor is a substance that slows down the action of the enzyme by binding at the active site of the enzyme preventing the binding of the substrate to it. It alters the catalytic activity of the enzyme either by slowing down or simply stopping the catalytic reaction.
