The crust is the innermost compositional layer of Earth.

Detailed explanation-1: -The inner most layer of earth is the core . The Earth is divided into 3 main layers. Crust (outermost), mantle and core (innermost). Option (a) is the correct answer.
Detailed explanation-2: -The inner core is the deepest layer on Earth. It is also made up of iron and nickel but the pressure is so high that it is no longer liquid.
Detailed explanation-3: -Layers based on chemical composition are the core, mantle and crust. According to mechanical properties, Earth’s layers are the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core, according to Phys.org (opens in new tab).
Detailed explanation-4: -The mantle lies below the crust and is up to 2900 km thick. It consists of hot, dense, iron and magnesium-rich solid rock. The crust and the upper part of the mantle make up the lithosphere, which is broken into plates, both large and small.
