Why is colonial mining considered a social question?

Correct answer: Because it could affect displacement labour exploitation and local livelihoods

The direct answer is D: colonial mining could cause displacement, labour exploitation and harm to local livelihoods. Mining is more than a technical activity because it uses land, water and labour and changes who controls resources. Step by step: a colonial authority or company identifies valuable minerals; land may be taken for mines, roads or railways; residents may be displaced; workers may face low wages, unsafe conditions or forced labour; farming, grazing, forests and water supplies may be damaged. Option D is correct because it connects resource extraction with social consequences. Option A is wrong because mining directly affects communities. Option B is wrong because benefits were not always equal and profits often favoured companies or colonial authorities. Option C is wrong because mining was not merely a scientific experiment. The question concerns social effects, while environmental effects are also important. Memory cue: for colonial mining, write resource, land, labour and livelihood.
