Which among the following events happened earliest ?
Explanation
Option (b) is correct because Dinabandhu Mitra published *Neeldarpan* in 1860, depicting the atrocities of indigo planters, which predates the other events. Satyendranath Tagore cleared the Indian Civil Services examination in 1863, making it the most tempting but incorrect choice as it occurred three years later. The core concept being tested is the chronological awareness of significant socio-cultural and administrative milestones in 19th-century British India.
