Answer:
C). An act of revenge.
Explanation:
Conflict in simpler terms is defined as the 'clash of interest.' If a character faces a clash of interest with another person(usually the antagonist) in the story, the most likely plot event that will lead him to develop as a character would be 'an act of revenge' as it will help him/her in recognizing their flaws and vices. This recognition would promote them to evolve as a righteous being by learning from their mistakes. This would justify himself/herself as an ideal hero/heroine of the story. Thus, option C is the correct answer.
