The correct option is A Ravi, Beas, and Satluj
The Indus river system is one of the major Himalayan river systems. Over a third of the Indus river basin is located in India whereas, the rest of the river basin lies in Pakistan. This led to several disagreements between the two countries and paved way for the Indus Water Treaty in 1960. The treaty gave Pakistan exclusive right over the western rivers - the Indus, Jhelum, and Chenab and those of the eastern rivers - the Ravi, Beas, and Satluj to India.
