B Correct answer
Explanation

Rats belong to the rodent family, which have incisors that grow continuously throughout their entire lifespan. This adaptation helps them maintain sharp teeth for gnawing, as the teeth are constantly worn down by their diet and behavior. While sharks also replace their teeth continuously, rats' teeth grow from the base rather than being replaced entirely.
