The correct answer is A. A tale is about to be told.
Step-by-step explanation:
The line of the story "It all began with Effie's getting something in her eye" tells the reader the beginning of the story was when Effie got something in her eye, and it is expected after this, the narrator continues adding details about what kind of thing Effie got in her eye and all the events that occurred later as a result of this. This implies this line introduces the setting and other basic elements of the story and suggests the narrator is about to tell the complete story or events related to this first important event. According to this, the correct answer is "A tale is about to be told."
