Indian Rivers and Waterways

The Kosi River, known as the 'Sorrow of Bihar,' causes massive flooding requiring evacuation of millions. Its unpredictable course changes and devastating floods make it one of the most dangerous rivers in India.

Goa is located along the banks of the Mandovi River, with its capital Panaji situated on the river's banks. The Mandovi is one of Goa's primary rivers, flowing through the heart of the state. Ganga flows through North India, Gomati through Uttar Pradesh, and Sabarmati through Gujarat.

Ahmedabad is situated on the banks of the Sabarmati River. The Sabarmati Ashram, Gandhi's residence during independence movement, is located on its banks. Narmada flows through Gujarat but not through Ahmedabad.

Narmada is the correct answer. It traditionally forms the boundary between North India and South India. The Narmada River flows westward and its valley has historically been considered the dividing line between northern and southern India. Tapi, Godavari, and Krishna are peninsular rivers but don't form this traditional boundary.

The rivers flowing into the Arabian Sea are Indus, Narmada, and Tapti. These are major west-flowing rivers of peninsular India. Kaveri flows eastward into the Bay of Bengal and is a peninsular river draining into the southeastern coast.

All four rivers - Brahmaputra, Ganga, Mahanadi, and Godavari - flow into the Bay of Bengal. These are major east-flowing rivers of India that form part of the vast Ganga-Brahmaputra-Mahanadi and Godavari drainage systems, eventually draining into the Bay of Bengal on India's eastern coast.

Sutlej is known as the Red River due to the reddish color of its waters in certain stretches, particularly near its origin in Tibet. This coloration comes from the red clay and sediment it carries. Penner, Chenab, and Beas are not commonly referred to as 'Red River'.

Penner (also known as Penna) River rises in the Nandi Hills of Karnataka. Kaveri originates at Talakaveri in Kodagu district; Krishna rises near Mahabaleshwar in Maharashtra; Bhima is a tributary of Krishna. The Nandi Hills are correctly associated with the Penner River's origin.

Nehru Setu Bridge, spanning the Sone River near Dehri-on-Sone in Bihar, is the longest railway bridge in India at 3,065 meters (approximately 3.1 km). Built in 1900 and later strengthened, it remains a vital rail link on the Howrah-Delhi main line.

The Ganga River is called the Padma in Bangladesh after entering the country from India. The Meghna is a separate river system that eventually joins the Padma, while the Tista (or Teesta) is a tributary that flows into both Bangladesh and India.

Kaveri River is traditionally called the 'Ganga of the South' or 'Dakshina Ganga' due to its sacred status in South India. It originates in Karnataka and flows through Tamil Nadu, supporting agriculture and culture similar to the Ganga's role in North India. The river hosts numerous temples and is central to Tamil heritage. Krishna, Godavari, and Narmada are major rivers but don't hold this specific title. Narmada is actually in central India, not the south.

The Gulf of Khambat (also known as the Gulf of Cambay) is located in India, on the western coast of the Indian state of Gujarat. It has no connection to the Bermuda Triangle, which is in the Atlantic Ocean near Florida and the Caribbean. Therefore, the statement is false.

Majuli (misspelled as Majauli in the question) is indeed the world's largest river island, located in the Brahmaputra River in Assam. It was formed by river channel changes and has a unique ecosystem with several satras (Vaishnavite monasteries).
