• C. They replace the need for punctuation.
• D. They have no impact on comprehension.

Answer: (B)

Transition words show connections between ideas, clarify relationships, and guide the reader through the text. In an argument or explanation, they help move from a claim to supporting reasons, evidence, and conclusions, acting like road signs that tell you what comes next and how ideas relate. They signal addition, contrast, cause and effect, or sequence to keep the flow smooth. Because of this, they improve flow and understanding rather than interrupt it. Using transitions thoughtfully helps your reader follow your logic and see how your points fit together.
