A. 2.6 - 3.0

B. 2.8 - 3.5

C. 3.0 - 4.5

D. 9.0 - 12

Answer: Option A

Solution(By Examveda Team)

The average density of the earth's crust is 2.6 - 3.0 Mg/m³.
The mass of the earth is the standard unit of mass in astronomy that is used to indicate the masses of other planets, including rocky terrestrial planets and exoplanets. The earth's core accounts for 15% of the earth's volume more than 30% of the mass, the mantle for 84% of the volume and close to 70% of the mass, while the crust accounts for 1% of the mass.
