The answer is C. the earths mantle because the wood in this case is the surface

Answer:

C. Earth's mantle.

Explanation:

Isostasy is a Greek word which means equal and standstill. In the theory of Isostasy its has been assumed that Earth's crust is floating over the earth's mantle and the flotation of crust at an elevation over mantle depends upon thickness and density of crust. In the whole scenario gravitational equilibrium should be maintained.
