B. Extra false rib
C. Extra true rib
D. First false rib

Answer 1

Hint: The cage in the body of animals and humans which is left uneaten by the carnivores is the rib cage. They are the long curved bones used to protect the heart and lungs. They give lungs the space to expand and relax while inhaling and exhaling.

Complete answer:
Ribs are the part of the vertebral column. There are 12 pairs of ribs in our body. They are the thin flat bones connected dorsally to the vertebral column. On the ventral side, they are connected to the sternum.
Ventrally they are attached to the sternum by hyaline cartilage. Thoracic vertebrae, ribs and sternum together are known as the rib cage.
The first 10 pairs are attached ventrally but the last two pairs that mean 11th and 12th rib pairs are not attached ventrally to the sternum so are called the floating ribs.
Sometimes people have one more pair of ribs that forms the 13th pair, which is called gorilla ribs as they are like distant cousins, gorillas.
So they will form the extra floating ribs.
Option A: Extra floating rib: the 11 and 12 ribs are the floating ribs, rarely someone has the 13 pair which is the extra floating rib.
Option B: Extra false rib: There sometimes arise the cervical rib from the 7th rib this can be called as the extra false rib as 1-7 ribs are the true ribs while the 8-10 rib pairs are called false ribs.
Option C: Extra true rib: there is no term like this.
Option D: First false rib: there is no term existing like this.

So the answer is option A: Extra floating ribs.

Note: Gorilla ribs are the rare characters of humans. Ribs can be broken by a traumatizing attack by some object or sudden movement by the body. Ribs are usually not eaten but form the leftovers of the non-vegetarian food. They are the long curved bones.
