1. D

Intrusive igneous bodies are rock bodies that are formed due to the flow of magma. In classifying igneous bodies, their size, shape, and relationship (s) with the surrounding rock layers are all considered.

2. B.

A batholith is the largest type of igneous body and it extends to unknown depths within the Earth's crust. These bodies are the size of mountains and are composed mainly of intermediate rock types like granite.

3. B

This igneous body is formed when magma intrudes into rock fractures and then crystalizes there. Through this crystallization, the newly formed rock cuts through the existing rock layers.
