Answer:
Among the options given on the question the correct answer is option A.
"My poor Sylvia's rose!" ejaculated Dr. Heidegger, holding it in the light of the sunset clouds; "it appears to be fading again. "
Explanation: "Dr. Heidegger's Experiment" is a short story from the writer Nathaniel Hawthorne's short story. On the story, the leading character Dr Heidegger is the old medical doctor who is experimenting on his four friends to prove that folly is not separate from the youth.
He believed that morality is associated with age. His experiment was related with fountain of youth and magic. He thought the drinking of water from fountain of youth will make him fool and never drank it.
However, the sentence,"My poor Sylvia's rose!" ejaculated Dr. Heidegger, holding it in the light of the sunset clouds; "it appears to be fading again" suggests the wisdom and reason of the character of Dr Heidegger.
Because, by the fading of the rose he showed that everything dies and it is the nature of life. So understanding this it shows his wisdom.He held the rose on the light of the sunset of clouds.But the rose did not grew or live. So he was reasoning himself.
