The correct option is C East Pakistanis sought refuge in India
During Indira Gandhi’s tenure, there was a lot of unrest in East Pakistan. Pakistan’s oppressive policies in East Pakistan resulted in a big movement there. This movement was led by Sheikh Mujibur Rahman and his organisation, ‘Mukti Bahini’. It resulted in millions of refugees coming to India from East Pakistan during that time. This unrest eventually led to another war between India and Pakistan.
