Option (D) is the incorrect statement. The Partition scheme did NOT include any official plan for transfer of population across the border. The context clearly states that the Partition was about 'drawing of the border demarcating the territory of each country' and dividing provinces like Punjab and Bengal on religious grounds. The large-scale migration of populations that occurred was a consequence of Partition, not something that was planned as part of the scheme. The context mentions 'large scale migration of Muslims to the newly created Pakistan' and 'displacement and rehabilitation' as outcomes, but nowhere does it state that population transfer was part of the original partition plan. The other options are correct: (A) Partition was indeed based on the 'two-nation theory' advanced by the Muslim League; (B) Punjab and Bengal were bifurcated according to religious majority; and (C) East Pakistan and West Pakistan were geographically separated by Indian territory and thus not contiguous.
