The correct answer is based on the common sources of Liquefied Petroleum Gas (L.P. gas), which typically includes hydrocarbons derived from natural resources. Crude oil is a major source of L.P. gas as it is extracted and refined into various petroleum products, including propane and butane, which make up L.P. gas. Similarly, wet gas wells, which produce natural gas that contains heavier hydrocarbons, can also be processed to yield L.P. gas.

In contrast, the other options do not typically produce L.P. gas. Alcohol and sugars mainly refer to renewable biomass sources and are not related to the production of hydrocarbon gases. Fruits and vegetables, while they may produce bioenergy through fermentation or digestion, do not yield L.P. gas. Lastly, although natural gas is technically a source, it is more relevant in contexts separate from crude oil and wet gas, making it less definitive than the correct choice that specifically emphasizes crude oil and wet gas wells.
