Yes, the answer is D. "For example" is a transition that is often used in compare and contrast essays to show a comparison between ideas. This transition is used to provide specific examples or instances that support the comparison being made. In a compare and contrast essay, using "for example" helps to clarify the similarities between the ideas being compared.
