Primary colour are :

Question

Accepted Answer

The question asks about primary colors, and the correct answer is given as Option 4: "All of these." Let's explore why this is the correct choice and why each individual option is part of the primary colors.

1. **Explanation for Option 4 (All of these):**
   - Primary colors are the set of colors that can be combined to create a broad spectrum of other colors. In the context of traditional color theory, particularly in art and design, the primary colors are red, blue, and yellow. These colors cannot be created by mixing other colors together, and they serve as the foundational colors from which other colors are derived.
   - Since Option 4 includes all three colors—yellow, red, and blue—it correctly identifies the complete set of primary colors in this context. Therefore, Option 4 is the correct answer because it encompasses all the primary colors.

2. **Explanation for why each of the other options is incorrect on its own:**
   - **Option 1 (Yellow):** While yellow is indeed a primary color, selecting only yellow does not provide the complete set of primary colors. It is only one part of the trio needed to mix other colors.
   - **Option 2 (Red):** Red is also a primary color, but like yellow, it is only one component of the full set. Choosing only red does not account for the other primary colors needed to form the basis of color mixing.
   - **Option 3 (Blue):** Blue is the third primary color, but on its own, it does not represent the entire group of primary colors. It is essential to include all three colors to have the complete set.

In summary, Option 4 is the correct answer because it includes all three primary colors—yellow, red, and blue—thereby providing the complete set necessary for color mixing in traditional color theory. Each of the other options, when considered individually, fails to represent the full range of primary colors.
