Indian Rivers and Waterways

The Godavari River is traditionally called the 'Ganga of the South' or 'Dakshin Ganga' due to its length and cultural importance. It is the longest river in peninsular India, flowing through multiple states. The Kaveri and Krishna are major southern rivers but shorter, and neither carries this epithet.

The Brahmaputra River originates in Tibet where it is called Tsangpo or Yarlung Tsangpo. It enters India in Arunachal Pradesh as the Dihang or Siang, becomes the Brahmaputra in Assam, and flows into Bangladesh as the Jamuna. This naming pattern reflects the river's journey through different regions and cultures.

River names are proper nouns and take 'the'. Superlative 'largest' also requires 'the'. Option C is correct because both blanks need 'the'.

Ox-bow lakes are formed in the lower course of a river where the gradient is gentle and the river meanders widely. When a meander loop becomes extremely curved, the river may cut across the neck during floods, abandoning the loop and creating a crescent-shaped lake. In the upper course, rivers are too fast and steep to form meanders, while the middle course is where meandering begins but ox-bow lakes are less common. The lower course's slow-moving water and flat land are ideal for ox-bow formation.

The Ganga river's total length is over 2500 kilometers (approximately 2525 km from its source in Gangotri to the Bay of Bengal). This makes it one of India's longest rivers. The 'Over 2500 km' option is the most accurate among the choices, as the precise length varies slightly depending on measurement methods but exceeds 2500 km.

Manali, a popular hill station in Himachal Pradesh, is situated along the banks of the Beas River. The Beas River flows through the Kullu Valley and Manali is a major town located on its banks. The Sutlej flows further east, while the Ganga flows through the plains.

The Periyar River in Kerala empties into the Arabian Sea at Parur (near Kochi). The Narmada and Tapti empty into the Gulf of Khambhat, while the Sabarmati empties into the Gulf of Kutch. Periyar is the only river among the options that flows into the Arabian Sea at Parur.

Srinagar, the summer capital of Jammu and Kashmir, is situated on the banks of the Jhelum River, which flows through the Kashmir Valley. The Indus flows through Ladakh, Shyok through Leh district, and Suru through Kargil district - none pass through Srinagar city.

Bhakra Dam is built on the Sutlej River in Himachal Pradesh. It's a major dam in India, part of the Bhakra-Nangal project. Narmada has its own dams, and Krishna is in southern India.

As data of three entities are given, we can call them statistics.

The Tsangpo River (known as Brahmaputra in India) enters India through Arunachal Pradesh after flowing through Tibet. It's one of the major Himalayan rivers. Singapore is a country, Hwanghoo is in China, making Tsangpo the only correct Tibetan river option.

ONGC (Oil and Natural Gas Corporation) conducted extensive geological surveys and explorations in Rajasthan and other western Indian regions to trace paleo-channels and underground water channels believed to be the ancient course of the Saraswati river. The Saraswati River Project involved scientific investigation of these dried-up river courses mentioned in Vedic texts.

The Danube River is the second-longest river in Europe and flows through multiple countries before emptying into the Black Sea via the Danube Delta in Romania. The Saint Lawrence flows into the Atlantic Ocean, the Zambezi into the Indian Ocean, the Godavari into the Bay of Bengal, and the Yamuna is a tributary of the Ganges.

Victoria Falls is located on the Zambezi River, forming the border between Zambia and Zimbabwe. It is one of the largest and most famous waterfalls in the world, known locally as 'The Smoke That Thunders'.
