Can you type the paragraph out in a comment?
The mood being shown here is pleasure and fulfillment. As the author talks about Montag he uses words such as amazing conductor. This shows how Montag enjoys his job, enjoys and takes pleasure into burning books. The author has Montag mock the burning books by saying he wants to shove a marshmallow on a stick in the furnace while they’re burning. Another reason could be when the author says a symbolic helmet numbered 451 showing that this is his duty and it’s his job to burn books.
B is correct because, in biography, the author choose someone that did something that influenced people.
