Concept:The Cripps Mission (1942) offered Indian dominion status and a post-war constituent assembly, but with controversial provisions allowing provinces to opt out.
Explanation:Option A is correct: The Cripps Mission arrived in March 1942 to seek Indian support for World War II.
Option B is correct: It proposed an elected Constituent Assembly (partly elected by provincial assemblies, partly nominated by princes).
Option C is correct: Any province unwilling to accept the new Constitution could form a separate Union or retain its existing constitutional provisions.
Option D is incorrect: The British government did not propose to enter into separate constitutional arrangements with provinces that acceded to the Union. Instead, a treaty was to be negotiated between the new constitution-making body and the British government to transfer power and protect minorities.
Thus, the false statement is the one suggesting the British could make separate deals with acceding provinces.
Answer:Option D is not correct.
