I believe the correct answer is: D. Fern has talked to them.
In the children’s novel “Charlotte’s web” written by an American
author E. B. White, Dr. Dorian says that he believes it is possible that
animals talk, if children say so. In his dialogue with Mrs. Arble, Dr. Dorian
explains that children pay more attention than adults and that he’s ready to
believe Fern, if she said that animals could talk:
“It is quite possible that an animal has spoken civilly to
me and that I didn’t catch the remark because I wasn’t paying attention.
Children pay better attention than grownups. If Fern says that the animals in
Zuckerman’s barn talk, I’m quite ready to believe her.”
