Question 3 options:

Switzerland produces power the North Sea.

Switzerland produces power from fast-flowing rivers.

Switzerland produces power from natural gas.

Switzerland produces power from coal.

I don't have much time no joke

The correct answer is: "Switzerland produces power from fast-flowing rivers. "

Electricity production in Switzerland has become an industry reliant mainly on hydroelectricity. The Alps cover two thirds of the territory of the country, hence, there are many mountain lakes and water reserves suitable for the generation of hydro power.

The water drained from the Alps is mostly used for run-of-the-river hydroelectricity (ROR) generation techniques. This mechanism requires power plants which do not need to store water, or just very small quantities. They contrast with traditional hydro power plants which are dependent on the existence of reservoirs.
