Answer
It deflects charged particles from the Sun

The correct answer is It deflects charged particles from the Sun — Choose the option that directly explains protection.

Step-by-step solution

  1. Read each option and relate it to the function of Earth’s magnetic field.
  2. Option a) attracts comets – the magnetic field does not attract comets.
  3. Option b) deflects charged particles from the Sun – this is the correct physical process.
  4. Option c) keeps Earth warm – temperature is mainly due to greenhouse gases.
  5. Option d) creates auroras – auroras are a visible effect of the same deflection.
  6. Choose the option that directly explains protection.
Common mistake: Choosing auroras as the protective mechanism

Concept tested: Magnetic field protection
