Explanation:

During the 20th century, Western nations' interest in Saudi Arabia was driven by the discovery of large oil reserves on the Arabian Peninsula. This resource was critical for Western industrialization, energy needs, and economic and strategic goals. The other options are incorrect: Saudi Arabia did not abandon Islamic law, European-style courts were not a core driver of Western interest, and modernization was not the primary motivating factor compared to oil.
