From baby to adult we have a different number of bones, due to certain bones fusing as we grow.

With this in mind, which statement is the most accurate?

a. 260 bones as a baby and 204 as an adult.
b. 261 bones as a baby and 205 as an adult.
c. 270 bones as a baby and 206 as an adult.
d. 271 bones as a baby and 207 as an adult.

Correct answer: c.

It is often stated that there are 206 bones in the skeleton, but this is only a typical adult count, not an invariable number. At birth there are about 270, and even more bones form during childhood. With age, however, the number decreases as separate bones gradually fuse.
