A significant challenge faced by Mizoram in its early years of statehood was:

Continuing insurgency
Economic underdevelopment
Inter-tribal conflicts
All of the above

The correct answer is: d) All of the above.

Mizoram is a state in northeastern India. It is the 23rd and most recent state to be formed in India, having been granted statehood on 20 February 1987. The state is home to the Mizos, a tribal people who speak the Mizo language.

Mizoram has a long history of insurgency. The Mizo National Front (MNF), a militant group, waged a long-running insurgency against the Indian government from 1966 to 1986. The insurgency was finally brought to an end with the signing of the Mizoram Peace Accord in 1986.

Mizoram is also a very poor state. The state’s economy is based on agriculture, and the majority of the population lives in rural areas. The state has a high rate of poverty, and many people lack access to basic amenities such as education and healthcare.

In addition to insurgency and economic underdevelopment, Mizoram has also been plagued by inter-tribal conflicts. These conflicts have been caused by a number of factors, including competition for land and resources, and ethnic tensions.

The challenges faced by Mizoram in its early years of statehood have been significant. However, the state has made progress in addressing these challenges in recent years. The insurgency has been brought to an end, the economy has grown, and the state has made progress in improving the lives of its people.
