The correct answer is C. Omniscient third person
Explanation:
In literature, the point of view refers to the type of voice or narrator that tells the events that occur in a story, common points of view include the first person that uses the pronoun "I" to tell the events of the story; second-person point of view that can be identified for the use of "you" and third person point of view.
In the case of the third person the events are told by someone who witnesses the events, but generally is not part of them and because of this the narrator uses the third person pronouns "she", "he", "it" or "they" to refer to the characters of the story. Additionally to this, a third person point of view can be limited if the narration is limited to the elements that can be observed or omniscient if the narrator knows the feelings, perspectives, thoughts and other inner processes of the characters.
Considering this, in the case of the passage presented the point of view is "Omniscient third person" because the narrator uses third-person such as "she" or "it" to describe the elements of the story, but also knows the feelings and perspectives of the character "the more nervous she became", "making everything seem spookier than it already was".
