If a very small amount of yellow is mixed into blue, the resulting green will lean more toward which primary colour?

Correct answer: Blue

The governing concept is colour bias created by unequal pigment proportions. Yellow and blue form green, but when only a very small amount of yellow is added, blue remains dominant in the mixture. Thus the green appears blue-green and option C is correct. Red and white are not the controlling colours in this two-pigment mixture.
