Most states in India are created on linguistic basis except Chattisgarh, Uttaranchal and Jharkhand. On what basis are these states created?

Ethnicity

The correct answer is Option (3) → Ethnicity

In the creation of three new states in 2000, namely Chhatisgarh, Uttaranchal and Jharkhand, language did not play a prominent role. Rather, a combination of ethnicity based on tribal identity, language, regional deprivation and ecology provided the basis for intense regionalism resulting in statehood.
