The answer is B. The higher the concentration of substrate, the FASTER a reaction happens (since there are more opportunities for molecules to collide in a way that favours the reaction), so B is an incorrect statement.

The other three options describe correct features of catalysts and/or enzymes (which are considered “biological catalysts”).
