Some of the options in this question are not correct; here is the correct and complete question:

In order for a fictionalized story to be based on real events, the author should include

A. Characters with strong feelings

B. Historical material

C. A narrator

D. Dialogue​

The correct answer is B. Historical material

Explanation:

Stories, novels, and poems are said to be based on real events if these include or are inspired by real people, settings, or historical events. This includes using any historical material and adapting it to create a story. For example, the play "The Tragedy of Julius Caesar" written by Shakespeare is a play based on real events as it includes real characters such as Julius Caesar and some of the events in it are based on historical events.

According to this, the element that is necessary to make a story to be based on real events is historical material. Also, others such as a narrator, dialogue, or characters with strong feelings can be found in most stories including those that are completely fictionalized.
