The correct answer is A, 'analyze'. When you analyze a character's actions, you are examining them and attempting to understand them. Answer choice B is incorrect, because gathering details about a character's actions does not necessarily mean that you understand them. Answer choices C and D are incorrect because they are part of the writing process, and when you examine a character's actions, you are typically reading.
Hope this helps!
