Explanation

The correct answer is C because the question is based on the Subtractive Color Model, which applies to pigments, dyes, and printing. In this model, the primary colors are Cyan, Magenta, and Yellow. When these colors overlap, they filter out certain wavelengths of light to create secondary colors. Statement 1 is correct because mixing Magenta and Yellow produces Red. Magenta absorbs green light and Yellow absorbs blue light, leaving only red light to be reflected. Statement 2 is correct because mixing Cyan and Magenta produces Blue. Cyan absorbs red light and Magenta absorbs green light, leaving only blue light to be reflected. Since both statements accurately describe the results of mixing subtractive primary colors, the answer is Both 1 and 2.
