Statement: A city administration has decided to install smart traffic signals at major intersections after observing a steady rise in road accidents during peak hours. The system will use real-time traffic data to automatically adjust signal timing based on vehicle density.
Conclusions:
I. The city administration assumes that better traffic flow management can help reduce accidents.
II. Real-time traffic data was not being used earlier to control signal timing at intersections.
III. All road accidents in the city are caused due to improper signal timing.
Which of the above conclusions logically follows from the statement?

Correct option is D

Explanation:
Conclusion I follows because the decision to install smart traffic signals after a rise in accidents shows that the administration believes improving traffic flow management can help reduce accidents.
Conclusion II follows because the statement says the new system will use real-time traffic data, which logically implies that such real-time data was not being used earlier.
Conclusion III does not follow because the statement does not say that all accidents are caused only by improper signal timing; it only mentions a rise in accidents during peak hours.
Hence, both conclusions I and II follow.
