The correct answer is (c) two months.
Section 144 of the Code of Criminal Procedure (Cr.P.C.) empowers a Magistrate of the first class to issue an order in urgent cases to prevent the commission of cognizable offences or to maintain public order. The order can be made for a period of two months, which can be extended by another two months.
The order can be made against any person or group of persons, and can prohibit them from doing certain acts or from being in certain places. The order can also be made to seize any property.
The order can be challenged in the High Court.
The other options are incorrect because they are not the correct period of validity of an order made under Section 144 of Cr.P.C.
