Concept:When a road is closed for several days, both on-ground traffic management and public notification are necessary.
Explanation:The statement says Grant Road will be closed for
3 days due to water pipeline work.
Course I: Increasing traffic police personnel at Grant Road will help physically coordinate and divert traffic.
This will reduce congestion and prevent chaos at the site.
So, course I logically follows.
Course II: Issuing a notification in major newspapers will inform the public about traffic diversions and alternate routes.
This will help people plan their journeys in advance during the closure.
So, course II also logically follows.
Hence, both courses of action are needed to handle the situation effectively.
Answer:Both I and II follow.
Therefore, the correct option is C.
