What kind of orange is generally formed by mixing equal amounts of red and yellow?

Correct answer: Balanced orange

The governing concept is proportion in colour mixing. Red and yellow combine to produce orange; when equal amounts of the two paints are used, neither colour dominates the mixture, so the result is generally a balanced or middle orange. Thus option C is correct. A green or blue bias would require another colour, and adding black would change the value rather than describe equal red-and-yellow mixing.
