{'gobar gas': [0, 0, 0, 1], 'methane': [0, 0, 0, 5], 'propane': [1, 0, 4, 4], 'main constituent': [0, 0, 1, 0], 'acetylene': [0, 1, 0, 0], 'ethane': [0, 0, 0, 2]}

The correct answer for the main constituent of Gobar gas is option 2: Methane.

To better understand the options and make an informed choice, let`s analyze each one:

1. Ethane: Ethane is a hydrocarbon gas that is commonly used as a fuel and a refrigerant. However, it is not the main constituent of Gobar gas.

2. Methane: Methane is the main constituent of Gobar gas (also known as biogas). It is a colorless and odorless gas that is produced by the decomposition of organic matter (such as animal dung or plant waste) in the absence of oxygen. Methane is a potent greenhouse gas and is commonly used as a source of energy.

3. Propane: Propane is another hydrocarbon gas that is commonly used as a fuel. While it can be a component of biogas in small amounts, it is not the main constituent of Gobar gas.

4. Acetylene: Acetylene is a highly flammable gas that is used for welding and metal cutting. It is not a constituent of Gobar gas.

In summary, the main constituent of Gobar gas is Methane, making option 2 the correct answer.
