Explanation:

Only statements 1&3 are correct.

• Modern Nationalism was unknown in India, yet the revolt of 1857 played an important role in bringing the Indian people together and imparting to them the consciousness of belonging to one country.

• It had seeds of nationalism and anti- imperialism, but the concept of common nationality and nationhood was not inherent to the revolt of 1857. Provincial roots of Indian nationalism, however, may be traced to the beginning of the era of crown rule in Bombay, Bengal, and Madras. By the year 1885, the thought of Nationalism was increasing rapidly among the Indians. Nationalism emerged in 19th-century British India both in emulation of and as a reaction against the consolidation of British rule and the spread of Western civilization. 

• One may say that the revolt of 1857 was the first great struggle of Indians to throw off British Rule. It established local traditions of resistance to British rule which were to pave the way for the modern national movement.

• Hindu Muslim Unity Factor- During the entire revolt, there was complete cooperation between Hindus and Muslims at all levels- people, soldiers, leaders. All rebels acknowledged Bahadur Shah Zafar, a Muslim, as the emperor and the first impulse of the Hindu sepoys at Meerut was to march to Delhi, the Mughal imperial Capital. Rebel and sepoys, both Hindu and Muslims, respected each other’s sentiments. Immediate banning of cow slaughter was ordered once the revolt was successful in a particular area. Both Hindus and Muslims were well represented in leadership, for instance Nana Saheb had Azimullah, a Muslim and an expert in political propaganda, as an aide, while Laxmibai had the solid support of Afghan Soldiers. Thus the events of 1857 demonstrated that the people and politics of India were not basically communal before 1858.

Hence option 1st is correct.
