The right answer is "A. The clergy "
You should be referring to the quote from "The Canterbury Tales" where the word gold is used to represent the clergy in all its purity that leaves it in such a high standard that nothing can reach it, just as gold can not be attained by rust.
The answer is D, as it describes to us on how you feel when u have a puppy for the first time.
Wouldn’t it be all of the above?
