Explanation:

• Statement 1 is incorrect: The Vishaka guidelines were a set of guidelines that were intended to protect women at the workplace. These were instituted by the Supreme Court of India in the year 1997.

• These are procedural in nature and state the method that is to be followed while dealing with cases related to the sexual harassment of women.

• Statement 2 is correct: The guidelines also lay down the obligation of the employer to file a complaint if the conduct towards an employee amount to a criminal offence which is punishable under the Indian Penal Code. The employer needs to initiate an action and ensure that the witnesses are not further victimized.

• Statement 3 is incorrect: The Vishaka guidelines were later on replaced by the Sexual Harassment of women at the workplace (prevention, prohibition and redressal) Act, 2013. The new act passed in 2013 broadens the definition of aggrieved women to involve women of all ages, in order to suit the modern-day conditions. It also broadens the scope of the term workplace which was earlier limited only to the traditional office set-up.

Hence option 2nd is correct.
