The correct answer is: a) Limited due to lack of navigable rivers.
Mizoram is a landlocked state in north-eastern India. It is bordered by Assam to the north, Tripura to the south, and Bangladesh to the west. The state is mountainous and has a dense forest cover. The major rivers in Mizoram are the Tlawng, the Tuirial, and the Chhimtuipui. These rivers are not navigable for long distances due to the presence of rapids and waterfalls. As a result, the role of waterways in Mizoram’s transport network is limited.
Option b) is incorrect because local transportation on some rivers is not significant. The rivers in Mizoram are not navigable for long distances, and as a result, they are not used for local transportation.
Option c) is incorrect because waterways are not significant for cargo movement in Mizoram. The rivers in Mizoram are not navigable for long distances, and as a result, they are not used for cargo movement.
Option d) is incorrect because waterways do play a role in Mizoram’s transport network, albeit a limited one.
