Explanation

Totalitarianism is defined precisely by the state's claim over both public and private life - it seizes the personal freedoms of individuals along with their political freedom, abolishes civil society, and is usually identified with a one-party state. The statement that it usurps political freedom but leaves personal freedoms intact is therefore the not-correct one. In the classic Friedrich-Brzezinski framework totalitarianism is treated as distinct from mere authoritarianism, so the first option stands as a correct characterisation.
