What is the significance of the odorant added to LP gas?

The significance of the odorant added to LP gas lies primarily in its role in enhancing safety. LP gas, in its natural state, is odorless, which makes it difficult for individuals to detect leaks. The addition of a distinct, strong odorant, typically ethyl mercaptan, serves the critical function of alerting people to the presence of gas. This prompts immediate action to mitigate potential hazards, such as fire or explosion, by locating and addressing the source of the leak. The detectable smell ensures that even small amounts of gas can be identified quickly, thus prioritizing safety in both residential and commercial environments where LP gas is used.

While odorants do not enhance the energy content, reduce flammability, or make the gas burn cleaner, their presence is crucial in providing a reliable warning system, underscoring why option B is the most appropriate answer.
