Uranium exploration has been conducted in parts of Manipur, but its commercial viability is:

Highly promising
Uncertain
Not feasible
Under assessment

The correct answer is: Uncertain.

Uranium exploration has been conducted in parts of Manipur, but the commercial viability of these deposits is uncertain. The deposits are located in remote areas and are difficult to access. The cost of extracting the uranium is also high. In addition, the environmental impact of uranium mining is a concern.

The government of Manipur has not yet made a decision on whether to develop the uranium deposits. The decision will depend on a number of factors, including the cost of extraction, the environmental impact, and the demand for uranium.

The following are the four options for the question:

  • Highly promising: This option is incorrect because the commercial viability of the uranium deposits in Manipur is uncertain.
  • Uncertain: This option is correct because the commercial viability of the uranium deposits in Manipur is uncertain.
  • Not feasible: This option is incorrect because the uranium deposits in Manipur are technically feasible to extract.
  • Under assessment: This option is incorrect because the commercial viability of the uranium deposits in Manipur is not under assessment.
