Answer:
<h2>D. Reading a text</h2>
Explanation:
Reading a text demands significant attention, so if a person is driving he or she shouldn't read any messages, because it implies a significant risk to her or his safety.
Actually, texting is the second activity that people tend to do while driving, putting others at risk.
Therefore, the right answer is D.
Additionally, other choices don't interfere with attention while driving.
