The volume of the earth consists of the following:
A. 1% Crust
B. 84% Mantle
C. 15% Core
Choose the correct option from the following:

Correct option is A

The correct option is (a) All A, B and C are correct. The volume distribution of the Earth's layers is approximately as follows:
 Crust (A): The Earth's crust makes up about 1% of its volume. It is the outermost layer, consisting of continental and oceanic crust.
 Mantle (B): The mantle accounts for about 84% of the Earth's volume. It lies between the crust and the core and is composed of silicate rocks that are rich in iron and magnesium.
 Core (C): The core, which includes both the outer and inner core, makes up approximately 15% of the Earth's volume. The core is primarily composed of iron and nickel and is responsible for the Earth's magnetic field.
