Correct Option: A

Nil Darpan is a Bengali play written by Dinabandhu Mitra in 1858–1859. The play was essential to Nilbidraha, or Indigo revolt of February–March 1859 in Bengal, when farmers refused to sow indigo in their fields as a protest against exploitative farming under the British Raj. It was also essential to the development of theater in Bengal and influenced Girish Chandra Ghosh, who, in 1872, would establish The National Theatre in Calcutta (Kolkata) where the first ever play commercially staged was Nildarpan.
