The correct answer is: b) Rare earth elements.
Rare earth elements (REEs) are a group of 17 elements that are essential for many modern technologies, including electric vehicles, wind turbines, and smartphones. They are also used in medical imaging, defense, and national security applications.
Sikkim’s mountainous terrain holds potential for undiscovered deposits of REEs. In 2018, the Indian government announced that it had discovered a large deposit of REEs in Sikkim. The deposit is estimated to be worth billions of dollars.
The discovery of REEs in Sikkim is significant because it could help India to reduce its dependence on imports of these critical minerals. India currently imports more than 90% of the REEs it consumes.
The development of the REE deposit in Sikkim could also create jobs and boost the economy of the state.
The other options are incorrect because:
- Uranium is a radioactive element that is used in nuclear power plants.
- Bauxite is an ore that is used to produce aluminum.
- Coal is a fossil fuel that is used to generate electricity.
