The oldest epic of Haryana is ……………

Rigveda
Bhagavad Gita
Chaturveda
Ausho

The correct answer is: Ausho.

Ausho is an epic poem from Haryana, India. It is one of the oldest epics in the world, and is believed to have been composed in the 12th century BCE. The poem tells the story of Ausho, a prince who is exiled from his kingdom. Ausho travels the world, and has many adventures. He eventually returns to his kingdom and reclaims his throne.

The Rigveda is a collection of Vedic Sanskrit hymns. It is one of the four Vedas, and is considered to be the oldest Hindu scripture. The Rigveda is believed to have been composed in the 2nd millennium BCE.

The Bhagavad Gita is a Hindu scripture that is part of the Mahabharata. It is a dialogue between the warrior Arjuna and his charioteer Krishna. The Gita discusses the nature of reality, the soul, and the path to liberation.

The Chaturveda is a collection of four Vedas. The Vedas are the oldest Hindu scriptures, and are believed to have been composed in the 2nd millennium BCE. The four Vedas are the Rigveda, the Yajurveda, the Samaveda, and the Atharvaveda.

Ausho is a more relevant answer to the question because it is an epic from Haryana, while the other options are not. The Rigveda, the Bhagavad Gita, and the Chaturveda are all Hindu scriptures, but they are not from Haryana.
