Final answer:
Jess thinks that Leslie has failed him because she didn't come to Terabithia. Option C is the correct answer.
Step-by-step explanation:
Jess thinks that Leslie has failed him because she didn't come to Terabithia. In the story 'Bridge to Terabithia' by Katherine Paterson, Jess and Leslie create an imaginary kingdom called Terabithia where they can escape from their daily struggles.
However, when Leslie doesn't show up one day, Jess assumes that she has abandoned him and their special place. This assumption leads him to believe that Leslie has failed him.
So Option C is the correct answer among the given options.
