Which one among the following statements is correct ?

The Revolt of 1857 was not supported by the Nizam of Hyderabad, Afzal-ud-Daulah, who remained a 'faithful ally' to the British throughout the rebellion [2]. While the revolt spread across Northern and Central India, many princely states, including Hyderabad and Gwalior, did not join the rebels. Specifically, the Scindhias of Gwalior did not give shelter to the Rani of Jhansi; instead, Maharaja Jayajirao Scindia refused her help, reported her movements to the British, and fled when rebels captured Gwalior [2]. Regarding other options, Dinabandhu Mitra authored the play 'Neel Darpan' about indigo planters, while 'Unhappy India' was written by Lala Lajpat Rai [1]. Mangal Pandey's actions occurred at Barrackpore in March 1857, where he was executed; he did not lead the sepoys' march to Delhi, which was initiated by the Meerut sepoys on May 10, 1857.
