Answer:

[tex]\boxed {\boxed {\sf D. \ The \ two \ substances \ have \ the \ same \ mass \ as \ the \ mixture}}[/tex]

Explanation:

The Law of Conservation of Mass states that matter/mass cannot be created or destroyed.

In a chemical reaction, this means that the mass of the reactants has to equal the mass of the products.

In this case:

  • The reactants are the two substances.
  • The product is the mixture.
  • They have to have the same mass

Therefore, the best answer choice is D: The two substances have the same mass as the mixture.
