In South Bihar, the locals have a common resentment against migrant traders and moneylenders. What are these migrant groups known as?

Dikus

The correct answer is Option (3) - Dikus

NCERT: Within south Bihar, adivasis shared a common hatred of dikus – migrant traders and moneylenders who had settled in the area and grabbed its wealth, impoverishing the original residents. Most of the benefits from the mining and industrial projects in this mineral-rich region had gone to dikus even as adivasi lands had been alienated. Adivasi experiences of marginalisation and their sense of injustice were mobilised to create a shared Jharkhandi identity and inspire collective action that eventually led to the formation of a separate state.
