Answer:
The answer is C: In the word impudent, the root is impu.
Step-by-step explanation:
A root word means is a word that you can add prefixes /beginnings) or suffixes (endings) to form new words. In this case the root word of impudent isn't "Impu", as "Im" is the prefix. The root is actually pude which comes from the latin pudendum and means to be able to do it. If we add the prefix "Im" then it's the opposite.
