D. Comparison/contrast 

In a compare/contrast essay, you can choose to use a block method or go point by point. In a block method, you would have a whole section on your first thing and then a whole section on your second thing. In these sections, the differences and similarities would be evident. Or, you could go point by point and show how each thing is similar/different on each specific issue.
