(i)
Tick (✓) the one statement in the table below which describes how HEP is generated.
|   | Tick (✓) | 
|  Atoms of uranium are split to create electricity. |   | 
|  Coal is burnt to produce steam which is used in the power station. |   | 
|  Running water turns a turbine to generate power. |   | 
|  Strong winds blow turbines to produce electricity. |   | 
|  Turbines are turned when the tide goes in and out. |   |
