C

In a perfect conductor, charges move freely. However, the distribution of charge is not always uniform, especially in the presence of external electric fields. The charges will redistribute until they reach equilibrium, but if the conductor is in a non-uniform external field, the distribution of charge will not be uniform. Hence, statement C is false.
Step 1: Recall that in electrostatic equilibrium, the electric field inside a perfect conductor is zero.
Step 2: Consider a conductor in a uniform electric field; charge will redistribute unevenly to counteract the field, leading to a non-uniform surface charge distribution.
Conclusion: Therefore, statement C is incorrect.
