The correct answer is: b) Seven major rivers of the Punjab region.
The Sapta Sindhu is a Sanskrit phrase that means “seven rivers”. It is mentioned in the Rig Veda, the oldest Hindu scripture, and is believed to refer to the seven major rivers of the Punjab region: the Indus, the Jhelum, the Chenab, the Ravi, the Sutlej, the Beas, and the Ghaggar-Hakra.
The Punjab region is located in the northwestern part of India and Pakistan. It is a fertile plain that is watered by the seven rivers. The region has a long and rich history, and was home to many ancient civilizations.
