Answer:
Option B is the correct answer.
Step-by-step explanation:
First of all, it is necessary to mention that characterization refers to provide a fictional character specific traits to create a specific role for this character. In this case, in option B we can see that Jim stared at her fixedly with that peculiar expression of face, even though Della did not know what it meant and made her feel terrified. By saying this, readers can infer that Jim was not sure about his feelings.
