Answer: Option D
Answer: (d)
Basic industries don’t depend on other industries to exist; their raw material is not the output of another industry, but rather their raw material is the stuff of nature itself.
The list of basic industries is short. Agriculture, ranching, fishing, forestry, mining, and petroleum constitute an exhaustive list. Strategic industries are industries that a country considers very important for its economic development or defence.
Critical industries are mostly related to infrastructure and communication. Any natural or manufactured material that contains at least 5% of one or more of the three primary nutrients - nitrogen (N), phosphorous (P), or potassium (K) - can be considered a fertilizer.
Industrially manufactured fertilizers are sometimes referred to as "mineral" fertilizers. Fertilizer production entails gathering raw materials from nature; treating them in order to purify them or increase their concentration; converting them into plant-available forms, and often combining them into products that contain more than one nutrient.
They are dependent on resources or goods that are externally procured.
