Final answer:
The apparent length of the tooth cannot be determined without more information.
Explanation:
The question asks about the apparent length of a tooth when observed by others. The actual length of the tooth is given as 5.00 cm. However, it is not specified how the length is being observed. Without more information, we cannot determine how long the tooth appears to observers. Therefore, none of the given options A, B, C, or D can be confidently chosen as the correct answer.
