#### Answer

This graph is a tree with six vertices whose degrees are 1, 1, 2, 2, 2, and 2.

#### Work Step by Step

This graph is connected and does not have any circuits. Therefore, this graph is a tree.
Vertex E and vertex F have degrees of 1. The other vertices have degrees of 2.
This graph is a tree with six vertices whose degrees are 1, 1, 2, 2, 2, and 2.
