The correct answer is: d) Indus.
Punjab is a region in South Asia that is located in the basin of the Indus River. The Indus River is the fifth-longest river in Asia and the 21st-longest river in the world. It flows through Pakistan and India, and it is the primary source of water for both countries. The Indus River is also an important source of irrigation for agriculture in the region.
The other options are incorrect because they are not major river systems that flow through Punjab. The Ganga River is a major river system that flows through India, but it does not flow through Punjab. The Brahmaputra River is a major river system that flows through India and Bangladesh, but it does not flow through Punjab. The Narmada River is a major river system that flows through India, but it does not flow through Punjab.
