B). To show how allusion can help the audience link information.
Explanation:
A thesis statement is illustrated as the statement that discloses the central idea, claim, or argument of an essay or research paper that the author intends to convey(also described as the author's purpose). It is usually mentioned in the introductory part of the paper or essay as the rest of the essay is built around it and functions to illustrate and substantiate the claim or argument proposed in it.
As per the given sample, the writer's purpose for the essay would be 'to reflect how allusion can aid the audience to link information' which he/she primarily wishes to convey as reflected by the thesis statement given. The rest of the essay could be based on validating this point to the audience by including evidence and counterclaims. Therefore, <u>option B</u> is the correct answer.
