The correct option is Crude oil.

Step-by-Step Explanation:

West Texas Intermediate (commonly abbreviated as WTI) is a specific grade or blend of crude oil. It is one of the major global benchmarks used for pricing oil, alongside others like Brent Crude and Dubai Crude.
WTI is described as a "light sweet crude oil" because of its relatively low density (light) and low sulfur content (sweet). This makes it highly desirable because it is easier and cheaper to refine into high-quality gasoline and diesel fuel compared to heavier, sourer grades of crude oil.
Therefore, the term refers directly to a grade of crude oil.
