Indian Rivers and Waterways

The Ganga was officially declared India's national river in 2008, recognizing its immense cultural, religious, and economic significance. It is considered sacred in Hinduism and supports millions of people.

The Ganga (Ganges) was declared the National River of India in 2008 by the Prime Minister to help achieve the objectives of the Ganga Action Plan. Yamuna, Cauvery, and Krishna are major rivers but do not hold the 'National River' status.

The Damodar River originates in the Chhota Nagpur Plateau of Jharkhand, specifically near the Chandwa area. It flows through Jharkhand and West Bengal. The Greater Himalayas, Eastern Ghats, and Western Ghats are geographically distinct mountain ranges located in different parts of the Indian subcontinent.

The Congo River crosses the equator twice - once flowing north from its source and again flowing south to its mouth. The Amazon crosses once, the Nile doesn't cross the equator (it flows from south to north but stays north of the equator for most of its course), and the Brahmaputra is in the Northern Hemisphere.

Panchavati is located on the banks of the Godavari River in present-day Nashik, Maharashtra. This is where Rama, Sita, and Lakshmana spent much of their 14-year exile. The Godavari is considered sacred in Hinduism and is the second-longest river in India after the Ganga.

The Brahmaputra River's name means 'son of Brahma' in Sanskrit ('Brahma' is the Creator god in Hinduism, 'putra' means son). The Ganga, Sutlej, and Krishna rivers are all major Indian rivers but none have names meaning 'son of the creator'.

Punjab derives its name from the Persian words 'Panj' (five) and 'Aab' (water), referring to the five rivers that drain the region: Beas, Sutlej, Ravi, Chenab, and Jhelum. Madhya Pradesh, Meghalaya, and Kerala are not named based on five-river systems.

The Indus River flows from Tibet through India and gives the country its name (derived from 'Sindhu', the Sanskrit name for Indus). It is one of the longest rivers in the world and was the cradle of the ancient Indus Valley Civilization. The other options are either not Indian rivers or are simply the country's name.

The Godavari River is indeed the longest river in southern India, stretching approximately 1,465 kilometers. While the Krishna (option A) is also a major peninsular river, the Godavari is longer and holds the distinction of being the longest in South India.

The Sardar Sarovar Dam is built on the Narmada River in Gujarat. It's one of the largest dams in India and part of the Narmada Valley Project. The Godavari, Krishna, and Tapi are other major peninsular rivers but don't host this particular dam.

Punjab derives its name from the Persian words 'Panj' (five) and 'Ab' (water), referring to the five major rivers of the region: Jhelum, Chenab, Ravi, Beas, and Sutlej. Uttar Pradesh, Madhya Pradesh, and Tamil Nadu are not associated with this description.

The Kosi river is called the 'Sorrow of Bihar' due to its frequent floods and devastating impact on the state. It's a tributary of the Ganges known for changing course and causing massive destruction, particularly in 2008.

The Damodar River is called 'Bengal's Sorrow' due to its frequent devastating floods in the Bengal region (now Jharkhand and West Bengal). The river's erratic flow and destructive floods earned it this epithet before the Damodar Valley Corporation project helped control flooding.

Chilka Lake (Chilika Lake) is located between the deltas of the Mahanadi and Godavari rivers in Odisha. It is Asia's largest brackish water lagoon. The Ganga flows far north, while Krishna and Kaveri deltas are in southern India.
