Answer:
A. The combustion of fossil fuels heats water to produce steam, which then turns a turbine.
Explanation:
Most heat-based generation of electricity uses steam and steam-driven turbines to actually turn the generator. This includes coal, oil, gas, and nuclear power, and some solar power as well.
The heat source is used to heat water, turning it to steam. The steam is then directed at a turbine, turning it and the attached generator to produce electricity.

In each experiment there have to be two groups - an experimental one (which has a different variable), and a control group. Both of these groups are subjected to the same thing except for that variable you are trying to test via an experiment.
