Explanation:

- The adult human body typically has 206 bones. This includes all the bones in the skeleton such as the skull, spine, rib cage, and limbs.

- Option 1 - 208: This is incorrect. While some sources mention additional small bones like sesamoid bones, the standard count is 206.

- Option 3 - 312: This number is incorrect. No human body naturally has this many bones.

- Option 4 - 300: Incorrect for adults. Newborns have around 300 bones, but they fuse as they grow, leading to the 206 bones in adults.
