Which of the following statements is incorrect?

Igneous rocks can be thought of as "primary" rocks because they crystallize from magma

Intrusive or plutonic rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface

The texture of an igneous rock is dependent on the rate of cooling

Intrusive rocks are fine grained and extrusive rocks are coarse grained

Explanation:

Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite.they are coarse grained.
Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include andesite, basalt, obsidian, pumice, rhyolite, scoria, and tuff. They are fine grained.
