The correct answer is B. 206.
The human skeleton is made up of 206 bones. These bones are divided into two main groups: the axial skeleton and the appendicular skeleton. The axial skeleton includes the skull, the spine, the ribs, and the sternum. The appendicular skeleton includes the arms, the legs, the hands, and the feet.
The skull is made up of 22 bones. The spine is made up of 24 bones, which are divided into the cervical vertebrae (7 bones), the thoracic vertebrae (12 bones), the lumbar vertebrae (5 bones), the sacrum (5 fused bones), and the coccyx (4 fused bones). The ribs are made up of 12 pairs of bones. The sternum is a single bone that is located in the center of the chest.
The arms are made up of 32 bones. The legs are made up of 30 bones. The hands are made up of 54 bones. The feet are made up of 52 bones.
The number of bones in the human skeleton can vary slightly from person to person. For example, some people may have an extra vertebra in their spine, while others may have fused bones in their hands or feet. However, the average number of bones in the human skeleton is 206.
Here is a brief explanation of each option:
- Option A: 212. This is incorrect because the human skeleton does not have 212 bones. The correct number of bones in the human skeleton is 206.
- Option B: 206. This is the correct answer because the human skeleton does have 206 bones.
- Option C: 202. This is incorrect because the human skeleton does not have 202 bones. The correct number of bones in the human skeleton is 206.
- Option D: 200. This is incorrect because the human skeleton does not have 200 bones. The correct number of bones in the human skeleton is 206.
