Answer:
a. Analytical.
Explanation:
There would be some who would argue and call it as an expository non-fiction work but that would be unfair as expository form only deals with the explaining of the topics which may include the news stories. But the articles provided in the newspaper, essays and biographies exemplify the analytical non-fiction works as it requires the analytical skills of the speaker. For say, if a writer is writing an article about increasing pollution or a road accident he or she will have to analyze the given data and present accordingly. However, the authors of these works have to act as a catalyst as the work should not have a single impression of their opinions and perceptions regarding the issue or person in case of a biography because this would turn the work into a biased and unauthentic one.
