An oil exploration company is engaged in extractive occupation.
Oil exploration companies search for oil reserves beneath the earth's surface and extract the oil using various methods such as drilling. This process of extracting resources from the earth is called extraction. Therefore, oil exploration companies are considered part of the extractive industry.
The extractive industry is one of the three main sectors of economic activity, along with the primary and secondary sectors. The primary sector involves activities related to the extraction of natural resources, while the secondary sector is concerned with manufacturing and processing raw materials into finished products.
Thus, the correct answer is that an oil exploration company is engaged in extractive occupation.
