Which statement is true about the appendicular skeleton of the human body? a. it consists of two groups, the bones along the main axis and the bones that connect the limbs to the axial skeleton. b. it consists of the vertebral column and all the bones that directly connect to it. c. it consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton. d. it consists only of the pelvic girdle and the bones that lie below it.

The appendicular skeleton.

A. It consists of two groups, the bones along the main axis and the bones that connect the limbs to the axial skeleton.

Explanation:

The Appendicular skeleton is the group of bones that hold the limbs, the pectoral griddle, and the pelvic griddle as well as uniting them to the axial skeleton. The axial skeleton is the group of bones composed by the skull, the vertebral column, and the thoracic cage. Thus, c and d options are incorrect because they only focus on one of the groups that compose the appendicular griddle. While b is incorrect because it describes the axis skeleton.
