The statement says that about twenty lakh people will visit the city during the ensuing festival. This means that there will be a large crowd in the city, which could lead to problems such as overcrowding, traffic congestion, and law and order issues.

Course of action I is to monitor the crowd and restrict entry of the people beyond a manageable number. This is a necessary step to ensure that the crowd does not become too large and unmanageable.

Course of action II is to put the local police authority on high alert to maintain law and order during the festival. This is also a necessary step to ensure that the festival is safe and peaceful.

Course of action III is to put all the hospitals in the city on high alert in case of any eventuality. This is a precautionary measure to ensure that there is adequate medical care available in case of any accidents or injuries during the festival.

Therefore, all three courses of action are necessary to ensure the safety and smooth running of the festival.
