The incorrect statement is B) It made the Central Executive responsible to the Legislature.
The Government of India Act, 1919 (Montagu-Chelmsford Reforms) introduced significant changes but did not make the Central Executive responsible to the Indian Legislature. At the centre, the Governor-General remained the head of the executive, and his Executive Council was responsible to the British Parliament, not the Indian Legislature. Responsibility to the legislature was partially introduced at the provincial level for ‘transferred’ subjects under the system of dyarchy.
Statement A is correct as the Act extended the principle of communal representation to Sikhs, Christians, Anglo-Indians, and Europeans. Statement C is correct as the Act is widely known as the Montagu-Chelmsford Reforms. Statement D is correct as the Act for the first time demarcated and separated the central and provincial subjects, laying a foundation towards a federal structure, though the system was still unitary in many respects.
