It comes from the heart, you have to be brave and strong to have courage.
The correct answer is A.
In his essay, "The Philosophy of Composition," Poe explains that he wanted to have a strong word for the Raven to say. It had to be "sonorous and susceptible of protracted emphasis".
These considerations led him to the conclusion that the word should contain the vowel "o" connected with the consonant "r."
After deciding these characteristics, the first word that came to his mind was "Nevermore."
B. would be the best choice to choose.
