Explanations:The Yamuna is a significant river in the Indian subcontinent and is one of the major tributaries of the Ganga. It originates from the Yamunotri Glacier in the Uttarakhand Himalayas and flows through several states before merging with the Ganga at Allahabad (Prayagraj). The Yamuna is crucial for the geography and economy of the region, particularly in the National Capital Territory of Delhi.
Delhi, the capital city of India, is situated on the banks of the Yamuna. The river plays a vital role in the city's water supply, supporting agriculture, industry, and domestic use. The Yamuna is also a significant cultural and religious river, with numerous ghats and temples along its banks in Delhi and other cities.
Understanding the geography of rivers and their tributaries is essential for various competitive examinations, especially those related to geography and general knowledge. The Yamuna's importance in the context of Delhi makes it a key river to remember for such examinations.
Other tributaries of the Ganga, such as the Chambal, Betwa, and Ghaghara, do not flow through Delhi. The Chambal and Betwa are located further south in Madhya Pradesh and Rajasthan, while the Ghaghara flows through the northern states of Uttarakhand and Uttar Pradesh. These rivers are significant in their respective regions but do not have a direct connection to Delhi.
Therefore, the correct answer to the question "Which tributary of river Ganga drains in Delhi?" is the Yamuna, as it is the only major tributary of the Ganga that flows through the National Capital Territory of Delhi.
