Step-by-step explanation:
When planning a narrative, several steps are fundamental to crafting a cohesive and engaging story. Among the options given, setting the scene and thinking of the plot events are critical components in the planning stage of a narrative. Setting the scene involves introducing characters, the setting, culture, background, and the initial situation. This step draws readers into the world of the narrative and provides context for the unfolding events. On the other hand, thinking of the plot events entails creating a plot diagram, focusing on the development of tension and conflict, and planning how it will be resolved in a meaningful way.
Building an argument is more pertinent to persuasive or expository writing rather than narrative writing.

Therefore, the correct step involved in planning a narrative from the given options is A. setting the scene as it is fundamental to establishing the foundation of the narrative. It acts as a springboard for the subsequent development of the plot and engages the audience from the very beginning.
