The correct answer is A. The author wants to present factual information effectively.
Explanation:
In general, the third-person point of view is objective and impersonal. Due to this, in the third-person point of view authors avoid the use of "I" (or related) that can introduce the author's point of view and the use of "you" that directly appeals to the audience. Instead, authors just report information using the pronouns they, she, he, it.
This occurs in the passage presented because the author focuses on describing the origin of fasting on Wednesday and the diverse responses of people to this without including personal opinions. Also, the author uses third-person pronouns, for example in "they are still observing the religious law". In this context, the author uses this point of view to present factual information effectively or create an objective/impersonal text (option A).
