Liquefied Petroleum (LP) gases are:

  1. butane and methane

  2. methane and propane

  3. propane and butane

  4. propane and natural gas

The correct answer is: butane and methane

Liquefied Petroleum (LP) gases primarily consist of propane and butane. These hydrocarbons are found in various natural gas deposits and are often separated from natural gas or produced alongside crude oil. The correct identification of LP gases as propane and butane is critical because these fuels are commonly used for heating, cooking, and as fuel for engines. The other options you considered include gases that do not fall under the definition of LP gases. Methane, for instance, is the primary component of natural gas, and while it is used for similar purposes, it is not classified as an LP gas. Therefore, the distinction between propane, butane, and methane is essential for understanding the categorization and applications of these gases in various industries.
