Explanation:

Both statements are incorrect.

Essential Defence Services Bill, 2021

• The Minister of Defence has recently introduced the Essential Defence Services Bill, 2021, in Lok Sabha.
• The bill provides for the maintenance of essential defence services so as “to secure the security of nation and the life and property of the public at large” and prevent staff of the government-owned ordnance factories from going on strike.
• The Bill seeks to empower the government to declare services mentioned in it as “essential defence services” and prohibit strikes and lockouts in any industrial establishment or unit engaged in such services.
• This is not for the first time that strikes by government employees are being made explicitly illegal by the government.
• The Madhya Pradesh (and Chhattisgarh) Civil Services Rules, 1965, prohibit demonstrations and strikes by government servants and direct the competent authorities to treat the durations as unauthorised absence. 

Constitutional Provisions

• Under Article 33 of the Constitution, Parliament, by law, can restrict or abrogate the rights of the members of the armed forces or the forces charged with the maintenance of public order so as to ensure the proper discharge of their duties and maintenance of discipline among them.
• Thus, for the armed forces and the police, where discipline is the most important prerequisite, even the fundamental right to form an association can be restricted under Article 19(4) in the interest of public order and other considerations.

Hence option 4th is correct.
