Between what ages does ossification generally end?

1. 5-10 years old

2. 16-25 years old

3. 30-40 years old

4. At birth

The correct answer is: 16-25 years old

Ossification is the process of bone formation that involves the replacement of cartilage structures with bone tissue. This process begins before birth and continues throughout infancy, childhood, and adolescence. It usually ends between the ages of 16-25 years old when the growth plates in bones fuse together to form solid bone. Option A is incorrect because at 5-10 years old, children are still in their growth stage and their bones are still developing. Option C is incorrect because at 30-40 years old, the body has already reached its peak bone mass and is starting to lose bone density. Option D is incorrect because at birth, most bones in the body are not yet fully formed and the process of ossification is ongoing. Therefore, option B is the correct answer as it is the most accurate representation of when ossification typically ends.
