Answer: C — 15 seconds

To avoid last-minute braking or the need to turn suddenly while driving in the city, it is important to look at least 15 seconds ahead. Looking far ahead allows you to anticipate potential hazards or obstacles in your path, giving you more time to react safely. This proactive approach to scanning the road can help you maintain a consistent speed, make smooth lane changes, and overall, drive more defensively. Looking further ahead also helps in maintaining a steady flow of traffic without abrupt stops or maneuvers, which contributes to safer driving conditions for yourself and others on the road.
