A Correct answer
Explanation

Natural gas is primarily composed of methane (CH4), typically 70-90% by volume. The remaining components include ethane, propane, butane, and other gases. Option A correctly identifies methane as the major constituent. CH3OH is methanol (alcohol), C2H6 is ethane (a minor component), and "None of these" is incorrect.
