The correct answer is: A. PQSR
Jawaharlal Nehru was the first to articulate the idea of a Constituent Assembly long before such an assembly was set up. The Cabinet Mission Scheme was a plan proposed by the British government in 1946 to resolve the constitutional deadlock in India. The scheme proposed the creation of a Constituent Assembly to draft a new constitution for India. Nehru was a strong supporter of the scheme and he played a key role in its implementation.
The other options are incorrect because they do not accurately reflect the sequence of events. Option B, QSRP, is incorrect because it places the Cabinet Mission Scheme before Nehru’s articulation of the idea of a Constituent Assembly. Option C, RPQS, is incorrect because it places the idea of a Constituent Assembly before the Cabinet Mission Scheme. Option D, SRPQ, is incorrect because it places Nehru’s articulation of the idea of a Constituent Assembly after the Cabinet Mission Scheme.
