- The Seventh Schedule to the Constitution of India deals with the division of powers between the Union and the States in terms of legislative subjects. It contains three lists: List I (Union List), List II (State List), and List III (Concurrent List). - a. Organisation of High Courts: Entry 78 of the Union List (List I) mentions "Constitution and organisation (including vacations) of the High Courts...". This means the Union Parliament has the power to legislate on the organisation of High Courts. - b. Taxes on Mineral Rights: Entry 50 of the State List (List II) mentions "Taxes on lands, buildings, mineral rights subject to any limitations imposed by Parliament by law relating to mineral development". While mineral development itself might involve Union regulation, the power to impose taxes on mineral rights, subject to parliamentary limitations, lies with the State Legislature. - c. Education: Entry 25 of the Concurrent List (List III) mentions "Education, including technical education, medical education and universities, subject to the provisions of entries 63, 64, 65 and 66 of List I; vocational and technical training of labour". Education was moved from the State List to the Concurrent List by the 42nd Constitutional Amendment Act, 1976. - Based on the above, the correct matching is: a - ii (Union List), b - iii (State List), c - i (Concurrent List).
