The correct answer is option C
Engaging the farmers in the mining activities would give them a source of income and will also save them from relocation thus it can be the best possible solution to the situation given.
The other solutions are not suitable as Bauxite mining and agriculture cannot take place at the same time. This is so because the extracts of mining would harm the agricultural produce. Since the government has already allocated the land to the miners, it is difficult that they would shift to another land. And if reclamation is provided after the min-ing has been removed, the quality of land may not remain suitable for agricultural activities.
