B. Fear
John was happy that he might meet Carolyn again after three years..but moving on further in to the short story..we notice that she accused him of being insensitive, even thoughtless!

These are just my thoughts, but I know the answer is B.
Wilde's short story "The Model Millionaire" represents the social strata of Victorian society in a lighter tone. There's Baron Hausberg, a millionaire, clearly a product of industrialization, who has got so much of money that if he's pleased by somebody, he wouldn't mind gifting him 10,000 pounds.
