What is a protagonist? a. the character or force that opposes the central characterb. the central character who is the focus of interestc. the hints or clues within a story that prepare the reader for the resolutiond. the central message or meaning of a story or poem 

The protagonist of a writing or work is the main character, also considered to be the good guy or hero in most circumstances. This is because even if a villain was a main character, you would be seeing the story through their eyes, a story to which they will most likely believe themselves to be good and righteous in their own way. Remember that an antagonist would be the opposing force to the central character or protagonist. 

The answer, therefore, would be B. the central character who is the focus of interest.
