Q:

C) Propane | D) Methane |
Answer: D) Methane
Explanation:
Explanation:
Natural gas is primarily composed of methane, but also contains ethane, propane, and heavier hydrocarbons.
Natural gas is a colorless, tasteless, odorless, and non-toxic gas. Because it is odorless, mercaptan is added to the natural gas, in very small amounts to give the gas a distinctive smell of rotten eggs. This strong smell can alert you of a potential gas leak.
It also contains small amounts of nitrogen, carbon dioxide, hydrogen sulphide and trace amounts of water.
