The correct answer is: Only I follows.
The statement says that there has been a large number of cases of internet hacking in the recent months, creating panic among the internet users. This means that there is a real and present danger to internet users, and that the government should take action to protect them.
Course of action I suggests that the government should make an all out effort to nab those who are responsible and put them behind bars. This is a reasonable course of action, as it would help to deter future hacking attacks and protect internet users.
Course of action II suggests that the internet users should be advised to stay away from using internet till the culprits are caught. This is not a reasonable course of action, as it would severely inconvenience internet users and would not be effective in preventing hacking attacks.
Therefore, the correct answer is: Only I follows.
