Answer:
A. At the resolution of the story, when the readers can see how the story ends.
Explanation:
The resolution of the story includes the settlement of the conflicts and as we know the themes illustrate the central idea or message of the author that he intends to convey is displayed through the solution of the issues and clashes. This assists every reader to relate themselves to the story and help them connect to the plot, actions, and consequences of the story i.e. in short "universal theme" displayed in a text. Thus, they need to analyze the actions that lead to the climax and final resolution. As without resolution they would not be able to efficiently get the author's message and may evoke an undesired response from them. So, the universal theme is usually revealed at the time of solution of the conflicts as incomplete actions may mislead the central idea of the author.
