The human body has a total of 206 bones. These bones make up the skeleton, which supports the body, protects organs, and allows movement.

At birth, humans have more bones—around 270—but many bones fuse together as we grow, leading to the adult total of 206 bones.

Bones come in different shapes and sizes and serve many purposes. For example, the skull protects the brain, the ribs protect the heart and lungs, and the long bones in the arms and legs help us move.

The skeleton is divided into two main parts: the axial skeleton (which includes the skull, spine, and ribs) and the appendicular skeleton (which includes the arms, legs, and pelvis).

Having the right number of bones and healthy bones is very important for body strength and function.

The other options are incorrect:
- 102 is too few bones.
- 306 is too many bones.
- 204 is close but not the exact number.

So, the correct answer is 206 bones.
