I need to know what Audrey Hepburn requested to eat instead of a
danish in the movie "Breakfast at Tiffany's"  was it a. a donut b. an
ice cream cone c. a peanut butter and jelly sandwich or d. an English
muffin?

Hello.

The answer is "ice cream cone."

Source: The Fairest Lady - Audrey Hepburn web site:
"That Audrey had quite a time trying to film the now famous opening
scene from "Breakfast at Tiffany's" in which her character stands
before Tiffany's, sipping coffee and eating a pastry. Audrey hated
pastries! She even suggested eating an ice cream cone instead, but
Blake Edwards (the director) finally coaxed her into eating the
pastry, and she did it beautifully."
