Answer:
The correct answer is option-sedimentary rock.
Explanation:
Rocks are classified on the basis of how they are formed into three types: Igneous rock, sedimentary rocks and metamorphic rocks.
Igneous rock is formed from the cooling of magma or lava which come out from the volcanic eruptions. Sedimentary rocks are formed by the accumulation and deposition of smaller sediments of rocks on the floor of the ocean or any other water bodies while Metamorphic rocks are formed due to heat and pressure in the Earth's crust.
Since the figure shows rock C formed by the accumulation and deposition of sediments this is "Sedimentary rock".
Thus, option-sedimentary rock is the correct answer.
