The correct answer is B. The third-person point of view is an observer with limited omniscience.
Step-by-step explanation:
In a third-person point of view, the narrator is in most cases an observer, and this uses third-person pronouns such as she, he, it or they in the story. This does not occur in the first-person point of view that uses the pronoun I and related words to it. The excerpt presented is an example of a third-person point of view due to the use of she and they in "The neighbors sometimes talked" and "She had no time no second of time to devote to the past".
Besides this, the third-person point of view is classified as limited omniscient if the narrator knows the thoughts, feelings, etc. of only one or a few characters. This occurs in the excerpt because the narrator describes the feelings fo Mrs. Sommers "She herself indulged in no such morbid retrospection" without referring to other characts. Thus, the point of view can be described as "The third-person point of view is an observer with limited omniscience".
