Indian Rivers and Waterways

After the 1947 partition, the Indus River flows primarily through Pakistan, with only its tributaries in India. The name 'India' indeed originates from 'Indus' (Sindhu). The upper reaches are in India, but the main course no longer flows through Indian territory.

The Krishna River originates in Maharashtra and flows through Karnataka and Andhra Pradesh before reaching the Bay of Bengal. It is one of the major peninsular rivers and its course is well-documented in Indian geography.

The statement is false because Mahakhali (also known as Mahakali) is a river in the Nepal-Uttarakhand border region and is a tributary of the Ghaghara/Karnali system, not directly of the Ganga. It joins the Ghaghara, which then joins the Ganga. The other rivers listed (Koshi, Gandak, Ghaghra, Yamuna, Son, Mahananda) are indeed Ganga tributaries, but including Mahakhali makes the statement false.

The Ganga (Ganges) is India's longest river, flowing approximately 2,525 km from its source in the Gangotri Glacier in Uttarakhand to its mouth in the Bay of Bengal. It is considered sacred in Hinduism and is a lifeline for millions.

Ahmedabad, the largest city in Gujarat, is situated on the banks of the Sabarmati River. The river is central to the city's identity and heritage, including Sabarmati Ashram where Gandhi began the Dandi March.

The Sone River is a principal southern tributary of the Ganges (Ganga) River. It originates near Amarkantak in Madhya Pradesh and joins the Ganga near Patna. The Sutlej, Brahmaputra, and Cauvery belong to different river systems.

The Sundarbans delta is formed by the confluence of the Ganges, Brahmaputra, and Meghna rivers. This is the world's largest delta region. The Padma is actually the name given to the Ganges in Bangladesh, so options including Padma separately are incorrect.

Mahatma Gandhi Setu is a bridge over the Ganges river (also called Ganga) connecting Patna to Hajipur in Bihar. It is one of the longest river bridges in India. Hooghly is a distributary of the Ganges in West Bengal, Gomati is a tributary in Uttar Pradesh, and Jamuna is a major river in Bangladesh.

The Coronation Bridge, also known as Sevoke Bridge, spans the Teesta River in West Bengal near Siliguri. It was built to commemorate the coronation of King George VI and Queen Elizabeth. The Torsha, Narmada, and Godavari are major rivers but not the one this bridge is located on.

Bhakra Nangal Dam, built across the Sutlej River in Himachal Pradesh, is indeed one of the highest gravity dams in the world at 226 meters. Hirakud Dam is across the Mahanadi, while Rana Pratap Sagar and Govind Sagar are reservoirs rather than dam names.

The Narmada Dam project (Sardar Sarovar Dam) has been India's most controversial due to environmental concerns, displacement of thousands, and prolonged legal battles. Other options like Koyna, Salia, and Dowleswaram have not faced similar levels of controversy.

Nagarjuna Sagar Dam is built across the Krishna River between Telangana and Andhra Pradesh. It is the world's largest masonry dam. Godavari, Torsha, and Narmada are other major rivers but not associated with this particular dam.

Krishna Raja Sagara (KRS) Dam in Karnataka, across the Cauvery River, is famous for its ornamental Brindavan Gardens attached to the reservoir. Bhakra Nangal is in North India, while Assan and Tunga Bhadra are not associated with Brindavan Gardens.

Farakka Barrage across the Ganga River in West Bengal is among the longest barrages in the world at 2.24 km. It was built to distribute Ganga waters between India and Bangladesh. Koshi, Assan, and Dowleswaram barrages are not of comparable length.
