The electric field lines in diagram D form closed loops, which would indicate the presence of a charge within the region. However, the prompt states that the region does not contain any charges, so this configuration is not possible. The other diagrams show electric field lines that do not form closed loops, which is consistent with the absence of any charges within the region.
