The question asks to identify the incorrectly matched pair of constitutional provisions and their sources. (1) Fundamental Rights are indeed borrowed from the USA. (2) Parliamentary Democracy is taken from Britain. (3) Directive Principles of State Policy are borrowed from Ireland. (4) Emergency Provisions are mainly inspired by the Government of India Act, 1935, and also influenced by the Weimar Constitution of Germany. The mention of Russia as the source for Emergency Provisions is incorrect.
