The structure of the substrate P and Q is mostly similar. This strong structural similarity would mean that the binding properties of these two different substrates might also be similar. The production of similar results by using substrate P instead of the substrate Q ensures this similarity. The substrate P binded with the enzyme similar to the substrate q and resulted in the same products.
Hence, the correct answer is 'Option C- P and Q have similar binding properties'.
