The correct answer is option 1. The partition of the Indian subcontinent was an attempt to stop conflict between Hindus and Muslims. In August 15th of 1947, the government decided that the partition was the best possible solution for the ongoing violent conflicts that were occurring between the Hindus and Muslims communities.
The territory that contained most of the Muslim community became Pakistan, while India retained the majority of the Hindus. Although the conflict subsided after the partition, both countries still have tensions between each other.
