Correct Answer: Chakkar

Solution : The correct option is Chakkar .

The word chakkar is not declared unparliamentary by the Lok Sabha Secretariat. The other three words, Shakuni, Nautanki, and Girgit, are all considered unparliamentary, as they are to be abusive, insulting, or defamatory. Shakuni is a character from the Indian epic Mahabharata who is known for his cunning and deceit. Nautanki is a Hindi word that refers to a type of theatrical performance that is often characterised by exaggerated gestures and melodrama. Girgit is a Hindi word for chameleon, and it is often used to describe someone who frequently changes their opinions or allegiances.
