The correct option is B Articles 20 and 21 cannot be suspended
Originally, on the Proclamation of National Emergency all the Fundamental Rights stand suspended automatically. But after 44th Constitutional Amendment Act, 1978 Articles 20(Protection in the conviction of offenses) and 21(Right to life and liberty) cannot be suspended. Moreover, Article 19 can be suspended in an emergency only if it is proclaimed on grounds of war and external aggression.
