  2. Neutron: no electrical charge✓ Correct

    A neutron is electrically neutral.

  3. Electron: negative charge✓ Correct

    An electron carries negative charge.

  4. Proton: negative charge✗ Incorrect

    Negative charge belongs to the electron, not the proton.

  5. Neutron: positive charge✗ Incorrect

    The neutron has no electrical charge.

Answer

A. Proton: positive charge · B. Neutron: no electrical charge · C. Electron: negative charge

Rationale

The three particle types can be distinguished by charge. Protons are positive, electrons are negative, and neutrons are neutral.
