Answer:
The correct answer is C. Earth's outer core contains liquids that conduct electricity.
Explanation:
The dynamo theory is a theory which describes why the Earth and other stars have a magnetic field. The dynamo theory proposes that an electrically conducting fluid, a conventional fluid or a rotating fluid can generate a magnetic field. Hence, these fluids are responsible for Earth's magnetic field.
The Outer core of the Earth exhibits dynamo. This is because Earth contains fluids inside its core which are rotating and driving convectional currents.
