The correct answer is Unlike in the USA, there is no dual system of courts.
– India has an integrated judicial system with the Supreme Court at the apex, followed by High Courts at the state level, and subordinate courts below them. Judgments of higher courts are binding on lower courts.
– In contrast, the USA has a dual system of courts: a federal judiciary system and separate state judicial systems, each with its own hierarchy.
– A) Dual citizenship: Incorrect. India has single citizenship.
– B) States have equal representation in the Council of States: Incorrect. Representation in the Rajya Sabha is based on population, not equal for all states.
– C) Persons belonging to the all-India services can be dismissed or removed by the States: Incorrect. Members of All India Services (like IAS, IPS) are appointed by the Union and are under the control of both Union and State governments, but disciplinary action like dismissal or removal requires Presidential approval.
