What is the primary use of LP-Gas?

The primary use of LP-Gas, or liquefied petroleum gas, is as a fuel for heating, cooking, and powering vehicles. This versatility makes it a popular energy source in both residential and commercial settings. In homes, LP-Gas is commonly utilized for heating systems, water heaters, and for cooking on gas stovetops and ovens because it burns cleanly and efficiently. In the context of vehicles, LP-Gas can be used in specially equipped cars as an alternative to gasoline or diesel, contributing to reduced emissions and lower fuel costs.

The other choices do not accurately represent the main applications of LP-Gas. Its role as a cosmetic ingredient, an agricultural-only product, or a cleaning agent is significantly less prevalent, which distinguishes the correct use of LP-Gas as a primary fuel source across various sectors. This broad application underscores why option B is the most accurate and commonly recognized primary use of LP-Gas.
