If more blue than yellow is used, which colour will be formed?

Correct answer: Blue-green

The governing concept is the effect of dominance in a colour mixture. Blue and yellow normally produce green; when blue is present in the greater proportion, the resulting green shifts toward blue and becomes blue-green. Therefore, option B is correct. Yellow-green would result when yellow dominates, while red-violet and yellow-orange involve red and do not match this mixture.
