1. The question asks where the 'Instrument of Instructions' from the Government of India Act 1935 were incorporated in the Constitution of India in 1950. 2. The 'Instrument of Instructions' under the 1935 Act were directives issued to the Governor-General and Governors regarding the exercise of their powers. 3. When drafting the Constitution of India, the framers drew inspiration from these instructions but adapted them for a democratic republic. 4. Option (1) Fundamental Rights (Part III) are justiciable rights guaranteed to citizens and are different in nature from instructions to the government. 5. Option (2) Directive Principles of State Policy (DPSP) (Part IV) are non-justiciable guidelines directed towards the State to achieve certain socio-economic goals. Dr. B.R. Ambedkar stated in the Constituent Assembly that the DPSPs were like the Instrument of Instructions, but addressed to the legislature and the executive. 6. Option (3) The Extent of executive power of State is defined in specific articles dealing with Union-State relations and executive functions, not directly incorporating the 1935 Instructions. 7. Option (4) The Conduct of business of the Government of India relates to procedural rules (like Article 77), distinct from the policy directives of the Instructions. 8. Therefore, the 'Instrument of Instructions' were essentially incorporated as the Directive Principles of State Policy (DPSP).
