Option C is correct because 'Panchnad' literally means 'five rivers' and refers to the five major tributaries of the Indus river system that flow through the Punjab region. These five rivers are the Sutlej, Beas, Ravi, Chenab, and Jhelum. The Indus is the main river into which these five tributaries ultimately flow, so it is not included as one of the 'five rivers' of Panchnad. Options A (Ravi), B (Chenab), and D (Jhelum) are all part of the five rivers of Panchnad, making them incorrect choices for this question.
