Which one of the following statements about the Cripps Mission is not correct ?

The correct answer is Option 4 because it contains a factual inaccuracy regarding the "non-acceding" provinces, making it the "not correct" statement among the choices.

• Option 1 is correct: Sir Stafford Cripps arrived in India in March 1942 to secure Indian cooperation for the British war effort during World War II.
• Option 2 is correct: The Mission proposed a post-war Constituent Assembly consisting of elected representatives from British India and nominated members from Princely States.
• Option 3 is correct: The proposal included a "provincial veto," allowing any province that did not accept the new Constitution to retain its existing constitutional status.
• Option 4 is incorrect: The British Government offered to enter into separate constitutional agreements only with non-acceding provinces (those opting out), not with "acceding" provinces. Provinces that joined the Union (acceding) would be bound by the common Constitution.

Therefore, Option 4 misrepresents the provision by applying the "separate arrangement" clause to the wrong category of provinces.
