The First sentence is where the quotation is used correctly- quotations is used with the titles of literary works and not with the name of the writers.
        
                    
             
        
        
        
Im guessing its B, Because it just makes more sense! I went in there and read it aloud using both words (A and B) B made more sense.

The meter from this line is pentameter, and to be more precise, this is an iambic pentameter.
Iambic means that the first syllable in the line is unstressed, and that it is followed by a stressed one. Here, you can see that DO in the beginning is unstressed, and the accent is placed on the second syllable, NOT. Pentameter means that there are five meters (penta means 5), and given that one meter consists of 2 syllables approximately, pentameter consists of 10 syllables in each line.
