B) Blue
C) Red
D) Black
E) Still white

Answer:

Green

Explanation:

This process of color subtraction can be represented by knowing that cyan light (a mixture of blue and green) shines upon the same magenta filter. Magenta absorbs its complementary color - green. Thus, green is subtracted from cyan light.
