Mahanadi flow into Bay of Bengal.

Mahanadi and Tapi (Tapti) are the two major rivers that flow into the Arabian Sea. Let's understand why these two rivers are the only ones that meet this criteria.

Mahanadi River:
- Originates: The Mahanadi River originates from the Sihawa Range in Chhattisgarh, India.
- Flow: It flows through the states of Chhattisgarh and Odisha.
- Delta: The river forms a large delta known as the Mahanadi Delta before emptying into the Bay of Bengal.
- Tributaries: The major tributaries of the Mahanadi River include the Seonath, Hasdeo, Ong, Jonk, and Tel rivers.

Tapi (Tapti) River:
- Originates: The Tapi River originates from the Multai region in the Betul district of Madhya Pradesh, India.
- Flow: It flows through the states of Madhya Pradesh, Maharashtra, and Gujarat.
- Delta: The river forms a small delta before merging with the Arabian Sea.
- Tributaries: The major tributaries of the Tapi River include the Purna, Girna, Panzara, and Arunavati rivers.

Reasons why these are the only major rivers flowing into the Arabian Sea:
1. Geographical Location: The Arabian Sea is located on the western coast of the Indian subcontinent, bordered by the Arabian Peninsula. The rivers flowing into the Arabian Sea are primarily located on the western side of India.
2. Western Ghats: The Western Ghats, a mountain range that runs parallel to the western coast of India, acts as a natural barrier for rivers flowing eastwards. This restricts the flow of major rivers into the Bay of Bengal and diverts them towards the Arabian Sea.
3. Drainage Patterns: The rivers on the western side of India have a different drainage pattern compared to those on the eastern side. The rivers on the western side generally flow in a westward direction and ultimately drain into the Arabian Sea.

Therefore, the Mahanadi and Tapi (Tapti) rivers are the only major rivers that flow into the Arabian Sea due to their geographical location and drainage patterns. The other options mentioned in the question, namely Yamuna, Brahmaputra, Ganga, Narmada, Godavari, and Kaveri, flow into the Bay of Bengal or have different outlets.
