If red and yellow are mixed unequally, with more red, which colour will be formed?

Correct answer: Red-orange

The governing concept is proportional colour mixing. Red and yellow are neighbouring warm colours whose mixture produces orange; when the quantities are unequal, the larger quantity influences the resulting hue. Because red is present in greater proportion, the orange shifts toward red and becomes red-orange. Yellow-orange would require more yellow, while green and blue-violet involve different colour relationships. Therefore, option B is correct.
