Explanations:The question asks about the river that flows into the Arabian Sea. To understand this, it is important to know the geographical locations and drainage patterns of the major rivers in India. The Arabian Sea is located to the west of the Indian subcontinent, and several rivers flow into it, including the Narmada, Tapti, and Luni.
The Narmada River is the fifth-longest river in India and is one of the most significant rivers that flow into the Arabian Sea. It originates in the Amarkantak hills in Madhya Pradesh and flows westward through the states of Madhya Pradesh, Maharashtra, and Gujarat before emptying into the Arabian Sea. The Narmada River is known for its ecological and cultural importance, and it is a major source of water for irrigation and drinking purposes in the regions it passes through.
On the other hand, the Kaveri River, Mahanadi River, and Krishna River all flow into the Bay of Bengal, which is located to the east of the Indian subcontinent. The Kaveri River is significant for the states of Karnataka and Tamil Nadu, the Mahanadi River is significant for the state of Odisha, and the Krishna River is significant for the states of Karnataka, Telangana, and Andhra Pradesh.
Therefore, the correct answer is the Narmada River, as it is the only river among the given options that flows into the Arabian Sea. Understanding the geographical locations and drainage patterns of rivers is crucial for comprehending the hydrological and ecological systems of a region.
