During lab, you will study tyrosinase activity by monitoring the color of the solution. As the reaction proceeds (and DOPA is oxidized), the concentration of dopachrome should increase in the solution. How should the solution change in color over time?

A. The solution will become a darker orange/brown.
B. The solution will become a darker red.
C. The solution will turn pink.
D. The solution will become clear.
E. The solution will not change color.
