(D) The human rib cage consists of $12$ pairs of ribs. Ribs $1$ to $7$ are called true ribs as they are attached directly to the sternum. Ribs $8, 9,$ and $10$ are called false ribs (vertebrochondral ribs) as they join the $7^{th}$ rib instead of the sternum. The last two pairs ($11^{th}$ and $12^{th}$) of ribs are not connected ventrally to the sternum at all and are therefore known as floating ribs.
