The correct answer is: d) All of the above.
Mizoram is a state in north-eastern India. It is hilly and has dense forests. The state has limited geological data. These factors make it difficult to explore for minerals in Mizoram.
Hilly terrain and dense forests make it difficult to access potential mineral deposits. The terrain is also difficult to work in, which can increase the cost of exploration and mining.
Limited geological data makes it difficult to identify potential mineral deposits. This is because geologists need to know the geology of an area in order to identify where minerals are likely to be found.
The combination of these factors makes it difficult to explore for minerals in Mizoram. This is a challenge for the state, as it could potentially have significant mineral resources.
