Verified step by step guidance

Understand the structure of the rib cage: The human rib cage consists of 12 pairs of ribs, which are categorized into true ribs, false ribs, and floating ribs.

Define true ribs: True ribs are the first seven pairs (ribs 1-7) that are directly attached to the sternum via their own costal cartilages.

Define false ribs: False ribs are the ribs that do not attach directly to the sternum. This includes ribs 8-12.

Differentiate floating ribs: Floating ribs are a subset of false ribs, specifically ribs 11 and 12, which do not attach to the sternum at all.

Identify the correct answer: Based on the definitions, ribs 8-12 are considered false ribs because they do not have a direct attachment to the sternum.
