Answer:
Green background is the correct answer.
Step-by-step explanation:
In arts, the dominant element is the one that attracts the attention of the public and it is noticed at the very beginning and it exhibits dominance over the other elements (that is the origin of the term.) The subdominant element gets less attention than the dominant one but is more important than the subordinate element, which is the one that receives less attention. Due to this, the correct answer is the green background.
