The adult human body typically contains 206 bones. This number represents the standard count of bones found in a fully developed adult skeleton. At birth, humans have approximately 270 bones, but as they grow, some of these bones fuse together, resulting in the 206 bones characteristic of adulthood.

The bones in the human body can be categorized into different groups such as the axial skeleton, which includes the skull, vertebral column, and rib cage, and the appendicular skeleton, which consists of the bones of the limbs and girdles. This structural organization plays a crucial role in protecting vital organs, facilitating movement, and supporting the body's structure.

The other choices reflect numbers that do not accurately represent the bone count in the typical adult human skeleton. For example, 198, 214, and 220 bones do not align with the known anatomical structure of an adult human body, as no recognized processes would lead to such counts in adulthood following the natural developmental cycle.
