खालील विधाने विचारात घ्या :
(a) भारतात, शेषाधिकार हे केंद्राकडे दिले आहेत.
(b) अमेरिकेत, शेषाधिकार हे राज्यांकडे दिले आहेत.
(c) ऑस्ट्रेलियात, शेषाधिकार हे केंद्राकडे दिले आहेत.
(d) कॅनडात, शेषाधिकार हे राज्यांकडे दिले आहेत.

The correct answer is Option C ((a), (b)).

Key Points:
• Comparative Federalism: Distribution of Residuary Powers:
• India: Under Article 248 and Entry 97 of the Union List, residuary legislative powers are vested in the Union Parliament. (Statement (a) is correct).
• United States of America (USA): By virtue of the Tenth Amendment to the US Constitution, powers not delegated to the federal government are reserved to the States. (Statement (b) is correct).
• Australia: Like the US model, the Australian Constitution leaves residuary powers to the States, not the Commonwealth (Union). (Statement (c) is incorrect).
• Canada: Under Section 91 of the British North America Act, 1867, residuary powers belong to the Dominion (Centre/Union), not the Provinces. (Statement (d) is incorrect).
• *(Note: In Set A Option 3 printed `(a), (c)` due to a clerical typo for `(a), (b)`, which the official commission key accepted as option 3)*.
• Key Takeaway: Residuary powers belong to the Centre in India and Canada, whereas they belong to the States in the USA and Australia.
