Solution

The correct option is B Long backbone and many interconnected muscles
A snake's body consists of hundreds of vertebrae and ribs. The length of a snake corresponds to its backbone length, which has numerous muscles supporting it. During locomotion, the backbone and associated muscles function together, thus making the snakes slither. The body shape of the snake may decide the speed of locomotion, but not its functional aspect.
