Question

For an autobiography, which element of your final draft will you consider to evaluate the richness of your details?

Answer 1

Organization is the correct answer

Answer 2

So, you're evaluating the richness of your details, that is, you want to know how rich your details are.

From the options provided, the best one is "elaboration": it can be understood as "adding details"  

But actually when you evaluate a text you wrote all of these options would be good to consider: so how good your organization is, etc.
