Answer
Brief Explanations:
The Earth's three main layers are the core (innermost), mantle (middle), and crust (outermost). Option A's "surface" is too vague. Option C lists inner and outer core (both part of the core layer) instead of the three main layers. Option D splits the mantle into upper and lower (sub - divisions of the mantle layer) rather than the three main layers.
Answer:
B. Core, mantle, and crust
