Explanation:

 No criminal proceedings can be started against the president and the governors in respect of their personal acts nor can they be arrested or imprisoned. However, ivil proceedings can be started against President and Governors during their term of office in respect of their personal Act by giving 2 months advance notice. so statement 1 is incorrect.

The constitution does not grants any immunity to the ministers for their official Acts. so statement 2 is incorrect.
The judicial officers enjoy immunity from any liability in respect of their official acts and hence, cannot be sued. The Judicial Officers Protection Act (1850) lays down that, 'no judge, magistrate, justice of peace, collector or other person acting judicially shall be liable to be sued in any civil court for any act done by him in the discharge of his official duty'. Statement 3 in correct. Hence, '1' is the right answer.
