{'main constituent': [0, 0, 1, 0], 'butane': [0, 0, 5, 5], 'methane': [0, 0, 0, 5], 'lpg': [0, 0, 2, 2], 'biogas': [2, 0, 1, 6]}

Option 1 states that the main constituent of LPG (liquefied petroleum gas) is butane. This is correct. LPG is a mixture of hydrocarbon gases, and butane is indeed one of the main constituents of LPG.

Option 2 states that the main constituent of biogas is methane. This is also correct. Biogas is mainly composed of methane, which is generated through the decomposition of organic matter by bacteria in the absence of oxygen.

Therefore, considering both statements, option 3, "Both 1 and 2," is the correct answer. Both statements are correct in identifying the main constituents of LPG and biogas respectively.

In summary, LPG mainly consists of butane, while biogas mainly consists of methane.
