Explanation:

Option (d) is correct: Barysphere is the central core of the earth. It is filled with molten magma with a large quantity of iron and nickel. Barysphere has two zones: the inner core region (~800 miles radius) and the outer core region (~1400miles radius). Supplementary notes: Parts of Earth The Earth consists of three parts as follows:

Barysphere: It is the central core of the earth. It is fi lled with molten magma with a large quantity of iron and nickel. Baryosphere has two zones: the inner core region (~800 miles radius) and the outer core region (~1400miles radius).

Pyrosphere: it is the middle part of the earth, also known as mantle. It is ~1800 miles in thickness and mainly consists of silica, manganese, and magnesium.

Lithosphere: it is the outermost region of the earth, also known as crust. It is 20-25 miles in thickness and mainly has silica and aluminum.
