Mizoram’s sole domestic airport is located in:

Aizawl
Lunglei
Champhai
Lawngtlai

The correct answer is: a) Aizawl.

Aizawl is the capital of Mizoram, a state in northeastern India. It is the largest city in the state, with a population of over 290,000 people. Aizawl is located in the southern part of the state, on the banks of the Tlawng River. The city is a major commercial and cultural center for the state.

The Aizawl Airport is the sole domestic airport in Mizoram. It is located about 10 kilometers from the city center. The airport has one runway and one terminal. It is served by several airlines, including Air India, IndiGo, and SpiceJet.

The other options are incorrect because they are not the locations of airports in Mizoram. Lunglei is a city in the southern part of the state, Champhai is a city in the western part of the state, and Lawngtlai is a town in the eastern part of the state. None of these cities have airports.
