The crust and upper mantle make up Earth’s
A
asthenosphere
B
core
C
continents
D
lithosphere
Explanation: 

Detailed explanation-1: -The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. Although the rocks of the lithosphere are still considered elastic, they are not viscous.

Detailed explanation-2: -The lithosphere is the outermost layer of Earth, composed of the crust and the brittle part of the upper mantle. The term lithosphere is derived from the Greek words “lithos, ” meaning stone, and “sphaira, ” meaning globe or ball.

Detailed explanation-3: -The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.

Detailed explanation-4: -Continental crust is less dense, thicker, and mainly composed of granite. 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.

Detailed explanation-5: -The correct option is A crust. The uppermost layer of the earth is called the crust. It is about 35 km on the continental masses and 5 km on the ocean floors.
