Concept:The extractive industry deals with occupations that obtain raw materials directly from natural sources.
Explanation:Such occupations involve removing natural resources like minerals, oil, gas, metals and aggregates from the earth.
Common examples are oil and gas extraction, mining, dredging and quarrying.
These are primary activities because they provide the basic raw materials before manufacturing or construction takes place.
They are not service or commercial occupations, so banking, trading and teaching do not belong to this group.
Answer:The occupations classified under the extractive industry are those involved in mining, quarrying, oil and gas extraction and dredging.
Therefore, choose the option that lists these extractive occupations.
