Answer:
B) near sea level
Explanation:
Firstly, Isostasy is an equilibrium of adjacent lithosphere floating on the asthenosphere . The continental crust been solid floats on the denser mantle and balance the equilibrium between the portion on the mantle and the elevated parts.
The higher it elevation on the lithosphere or continental crust the more portion of the crust that sinks into the aesthenospere to balance the equilibrium. Therefore to balance a 40km thickness of continental crust requires more portion sinking into the interior of the earth(mantle) .
Both continental crust(40km and 20km) will be near sea level to be in equilibrium.

The correct answer is - A. Amazon Jungle.
The Amazon Jungle will have the fastest rate of weathering by far compared to the other suggested locations. The reason for that is that the weathering is the fastest at places where there's high temperatures, high precipitation, high humidity, and lot of vegetation. The Amazon Jungle has all of this characteristics. The high temperatures, rainfall, humidity, and vegetation, combined will contribute to mechanical and chemical weathering, that will take place constantly throughout the year, thus the rocks, or any other disposable material will not last for a long period of time in those circumstances.
