The most important industry on the Arabian Peninsula is B) Harvesting and refining of oil and natural gases. Saudi Arabia, which dominates the region both in size and oil resources, is home to around 25% of all the known oil reserves in the world. Although the region has started exploring diverse economic sectors such as service industry, construction, tourism, and education to prepare for a future when oil reserves are depleted or less in demand, the oil and gas industry remains the economic backbone of the peninsula. It is also a strategic component globally, given the substantial contribution these resources make to the international energy market.
