Which of the following is/are west- flowing river(s) of India? 1. Mahanadi 2. Krishna 3. Narmada 4. Cauvery Select the correct answer using the code given below.

The drainage system of Peninsular India is primarily divided by the Western Ghats. Most major rivers, including the Mahanadi, Krishna, and Cauvery (Kaveri), flow eastwards and drain into the Bay of Bengal [4]. The Mahanadi flows through Chhattisgarh and Odisha into the Bay of Bengal [2]. Similarly, the Krishna and Cauvery originate in the Western Ghats and flow eastwards, forming deltas at their mouths [4]. In contrast, the Narmada and Tapi are the only long rivers that flow westwards through rift valleys to discharge into the Arabian Sea [2]. While the Mahanadi, Krishna, and Cauvery are classified as east-flowing consequent rivers, the Narmada is a major exception that flows west, making it the only west-flowing river among the options provided [2].
