Which statement about the methane content of natural gas is correct?

• A. Methane makes up about 85-95% of natural gas
• B. Methane makes up 5-15%
• C. Methane makes up 100%
• D. Methane is not present in natural gas

Answer: (A)

Natural gas is dominated by methane, which is the main component by volume. In typical natural gas, methane makes up roughly 85 to 95 percent of the mixture. The remaining portion consists of smaller amounts of other hydrocarbons (like ethane and propane), carbon dioxide, nitrogen, and trace impurities. So this statement aligns with how natural gas is actually composed, while the other options either underestimate, claim there is no methane, or assert methane is the only component.
