Solution

The correct option is B

b) It is a frozen mixture of water and concentrated natural gas


B)

Explanation:

Commercial development of the globe’s huge reserves of a frozen fossil fuel known as “combustible ice” has moved closer to reality after Japan and China successfully extracted the material from the sea floor off their coastlines.

Combustible ice is a frozen mixture of water and concentrated natural gas. Technically known as methane hydrate, it can be lit on fire in its frozen state and is believed to comprise one of the world’s most abundant fossil fuels.
