Which one of the following sets of commodities are exported to India by arid and semi-arid countries in the Middle East?

1. Arid and semi-arid countries in the Middle East are major producers and exporters of petroleum and related products. 2. While some countries in the region produce dates and other fruits, large-scale export of diverse fruits to India is less characteristic than petroleum. 3. Palm oil is primarily exported by Southeast Asian countries (like Indonesia, Malaysia), not typically Middle Eastern arid countries. 4. Precious stones and pearls historically came from the region (especially pearls from the Gulf), and continue to be traded, often involving re-export hubs like Dubai. This remains a significant export category. 5. Raw wool and carpets are produced but might not be the primary exports compared to other items. 6. Perfume (especially traditional attars) is associated with the region, but coffee originates from regions like Yemen historically, though large-scale export to India compared to other goods is questionable. 7. Considering the major exports, precious stones and pearls fit as a significant category historically and currently traded from the Middle East to India.
