Answer

Brief Explanations:

An opinion is a subjective statement that reflects a person's belief or judgment. Options A, B, and C are factual statements about the mantle. Option A is a fact about its mass contribution, Option B is a fact about heat movement (convection currents), and Option C is a fact about its chemical composition. Option D, "It is the most important layer of the earth," is a subjective opinion as what constitutes "most important" can vary depending on one's perspective.
