The correct answer is: Only I and II follow.
The statement says that there has been an unprecedented increase in the prices of essential commodities during the past few days due to the strike call given by the transporters association. This means that the strike has caused a shortage of essential commodities in the market, which has led to an increase in prices.
Course of action I is to order the transporters’ association to immediately withdraw the strike call. This is a reasonable course of action because it would help to resolve the shortage of essential commodities and bring down prices.
Course of action II is to make alternative arrangements to ensure adequate supply of essential commodities in the market. This is also a reasonable course of action because it would help to address the shortage of essential commodities and bring down prices.
Course of action III is to declare the strike illegal and put all those responsible for the strike behind the bars. This is not a reasonable course of action because it would not help to resolve the shortage of essential commodities and bring down prices. In fact, it could make the situation worse by further disrupting the supply of essential commodities.
Therefore, only courses of action I and II follow.
