In the given question, a statement of Assertion is followed by a statement of Reason. Mark the correct answer.

Assertion: Before Partition Congress had agreed to grant considerable autonomy to the provinces.
Reason: They wanted to assure the Muslim League that within the provinces where the Muslim League came to power the Centre would not interfere.

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

Before Partition Congress had agreed to grant considerable autonomy to the provinces. This had been part of an effort to assure the Muslim League that within the provinces where the Muslim League came to power the Centre would not interfere. After Partition, most nationalists changed their position because they felt that the earlier political pressures for a decentralized structure were no longer there.
