The correct answer is E. All follow.
The statement says that incessant rain has posed the problem of overflowing and flood as the river bed is full of silt and mud. This means that the river is likely to overflow its banks and cause flooding in the areas near the river. To prevent loss of life and property, the people residing near the river should be shifted to a safe place. The people should also be made aware about the imminent danger over radio/television so that they can take necessary precautions. After the flood has receded, the silt and mud from the river bed should be cleared to prevent future flooding.
Option I: The people residing near the river should be shifted to a safe place.
This is a necessary course of action to prevent loss of life. If the river overflows its banks, the people living near the river will be in danger. They should be shifted to a safe place as soon as possible.
Option II: The people should be made aware about the imminent danger over radio/television.
This is also a necessary course of action. The people living near the river need to be aware of the danger so that they can take necessary precautions. They should be told to stay away from the river and to move to a safe place if the river starts to overflow.
Option III: The silt and mud from the river bed should be cleared immediately after the receding of the water level.
This is a necessary course of action to prevent future flooding. If the silt and mud are not cleared, they will build up in the river bed and make it more likely that the river will overflow in the future. The silt and mud should be cleared as soon as possible after the flood has receded.
