Answer 2

The correct answer is "The type of mineral in the rock".

Step-by-step explanation:

Rocks are classified mostly by its texture and its composition. When a rock is classified based on its composition the feature that is most used is the type of mineral in the rock. For instance, igneous rocks are made of silicate minerals, while quartz, K-feldspar, and muscovite are found in sedimentary rocks.
