Sustainable urban mobility requires shifting people out of private cars and into higher-capacity, lower-emission modes, so...

1. Relevant knowledge points and concepts
- Sustainable cities: aim to reduce traffic congestion, greenhouse-gas emissions, and air pollution while improving accessibility.
- Modal shift: moving trips from private vehicles to public transport, walking, and cycling increases person-throughput per road space and lowers per-capita emissions.
- Public-transport investment effects: better frequency, coverage, and reliability make transit attractive, enabling equity and reducing vehicle ownership and use.

2. Step-by-step reasoning
- The author’s likely stance is judged by which option aligns with sustainable-transport principles.  
- Option b states that investment in public transportation is essential for creating sustainable cities. This directly addresses capacity (moving more people efficiently), environmental goals (lower emissions per passenger), and urban planning (reducing need for road expansion).
- If the passage argued for reduced congestion, improved air quality, and sustainable urban design, promoting public transit investment is the logical policy recommendation to achieve those goals.

3. Calculations (none needed)
- No numerical computation is required for this inference question.

4. Why the correct answer is correct
- Investing in public transport is a widely accepted, evidence-based approach to achieving sustainable cities because it: (a) increases mobility for many people without proportionally increasing road space, (b) reduces per-passenger energy use and emissions compared with private cars, and (c) supports compact land use and equitable access—objectives consistent with a pro-sustainability author.

5. Why the other options are incorrect
- a. “Private cars are the most efficient solution” contradicts sustainability goals; private cars have lower person-throughput and higher emissions per traveler.
- c. “Urbanization has minimal impact on congestion and air pollution” is false—urbanization typically intensifies congestion and local pollution unless mitigated.
- d. “Walking and cycling do not significantly contribute” is incorrect because active modes are key components of reducing short car trips and overall vehicle reliance.

6. Conclusion
Therefore, option b (Investment in public transportation is essential for creating sustainable cities) is the best choice and matches the provided correct answer.
