Answer: The rock which is made up of molten magma is igneous. Igneous rocks are formed from the cooling and solidification of molten magma or lava. They are the first type of rock to form in the rock cycle and are also known as primary rocks. Thus, the correct answer is option C.

Complete Answer:

Igneous rocks are formed when molten magma cools and solidifies. This process can happen beneath the Earth’s surface or after a volcanic eruption on the surface. When magma cools inside the Earth, the rocks formed are called intrusive igneous rocks (e.g., granite). These rocks cool slowly, so they have large crystals. When magma comes out on the surface as lava and cools quickly, it forms extrusive igneous rocks (e.g., basalt). These rocks cool so fast that they often have very small or no crystals.

Thus, the rock which is made up of molten magma is igneous.

Igneous rocks are also called primary rocks because they are the first to form and do not come from any other type of rock. They are generally hard and strong. Some have a glassy appearance, while others are grainy. These rocks do not contain fossils because the heat of the magma or lava would destroy any organic matter.

Igneous rocks are important because they form the foundation of the Earth’s crust. They also contain valuable minerals like mica, quartz, and feldspar. Over time, weathering and erosion break these rocks into smaller pieces, which may eventually form sedimentary rocks. Thus, igneous rocks play a key role in the rock cycle.
