Formal approach is the best tone to use.

Individuals in life or death situations should not be held accountable for their action. They are obviously going to want to be alive and happy, and not die or live in misery, so victims would most likely do whatever it takes to survive. Whoever made the decisions weren’t fully thinking it through because we all develop mentally at a different age for children and adults. Individuals who are in life or death situations don’t put themselves in that positions purposely to where they know they can die. In situations like these, everyone feels stress to the point where they have no other option until it is too late when they make their final choice

B is correct "A social commentator, who explains what a book says about people in general."
Restatement
Explanation
Example
Conclusion
From my my experience this usually differs depending on the type of book it is, but I think the best choice is either A, to help the reader understand new concepts, or C., It allows the reader to focus on key ideas and information during the reading. I'd pick C though, since it's more in depth and makes more sense.
B. doesn't make that much sense unless the book is an argumentative or a persuasive book.
D. only applies to personal narratives. Nobody can understand a writer's personal experiences and attitudes otherwise.
