I'm not familiar with the book but the conflict is usually a fairly easy thing for me to find (I know some struggle with it) what you should do is summarize what you've read. Take that summery and think "alright, the character is facing an issue with_______" (his conscience, another character, society, or nature) and once you summarize it, the rest should be fairly simple. Hopefully this helps.
The correct answer is c. You shouldn't pat a strange dog; sometimes they're not friendly.
