Which of these statements concerning ribs is true?
A)there are five pairs of floating ribs
B)floating ribs do not attached to vertebrae
C)the head of the rib attaches to the manubrium of sternum
D)the true ribs attach directly to the sternum with coastal cartilage
In this question answer given in TRUE MAN is (D) but I think answer should be (B) because floating ribs are not attached to sternum and also they are false ribs.So,what us the answer now?

Ribs 1–7 are classified as true ribs (vertebrosternal ribs). The costal cartilage from each of these ribs attaches directly to the sternum. Ribs 8–12 are called false ribs (vertebrochondral ribs). The costal cartilages from these ribs do not attach directly to the sternum. For ribs 8–10, the costal cartilages are attached to the cartilage of the next higher rib. Thus, the cartilage of rib 10 attaches to the cartilage of rib 9, rib 9 then attaches to rib 8, and rib 8 is attached to rib 7. The last two false ribs (11–12) are also called floating ribs (vertebral ribs). These are short ribs that do not attach to the sternum at all. Instead, their small costal cartilages terminate within the musculature of the lateral abdominal wall.
The floating rib refers to the two lowermost, the eleventh and twelfth, rib pairs; so-called because they are attached only to the vertebrae–and not to the sternum or cartilage of the sternum
From tabove i think option D is correct not option B
So TRUE MAN is correct
