Answer: (D)

Verified step by step guidance

1. Understand the pharmacological effects of cocaine on the central nervous system, noting that it is a stimulant that increases dopamine levels, leading to heightened alertness and energy.
2. Recognize that while cocaine may temporarily improve certain cognitive functions like reaction time, it also significantly impairs judgment and decision-making abilities.
3. Consider how impaired judgment and increased risk-taking behavior can negatively affect driving, making it more dangerous despite any perceived improvements in concentration.
4. Compare the effects of cocaine on driving with those of other substances, such as alcohol, to understand that cocaine does not cause drowsiness but rather leads to reckless behaviors.
5. Conclude that the most dramatic effects of cocaine on driving are increased risk-taking and impaired judgment, which contribute to dangerous driving behaviors.
