Which elements are abundant in the formation of interior layer of the earth Nife?
Detailed Explanation:
The Earth's core, called Nife, is composed primarily of nickel (Ni) and iron/ferrum (Fe), making it the densest layer (density 9.5–14.5 g/cm³).
The mantle is made of silicon and magnesium (Sima), while the crust consists of silicon and aluminium (Sial)—neither forms the core.
Therefore, nickel and ferrum are abundant in Nife, making Option 3 the correct answer.
