Which statement correctly explains the importance of Devprayag?

Correct answer: After Bhagirathi and Alaknanda meet the river is called Ganga

The direct answer is A: after the Bhagirathi and Alaknanda meet at Devprayag, the combined river is called the Ganga. Devprayag is an important confluence in the Himalayan drainage system. A confluence is a place where two rivers join. Here, Bhagirathi and Alaknanda are two important headstreams. Step by step: Bhagirathi flows from the Gangotri region; Alaknanda flows through the Himalayas; they meet at Devprayag; after this meeting, the river receives the name Ganga. Option A is correct because it gives this exact geographical fact. Option B is wrong because Yamuna and Chambal do not meet at Devprayag; this is not the defining importance of the place. Option C is wrong because Brahmaputra is not renamed Jamuna at Devprayag; Jamuna is the name used for the Brahmaputra in Bangladesh. Option D is wrong because Narmada flows westward and reaches the Arabian Sea, but not at Devprayag. Do not confuse Devprayag with Prayagraj: Devprayag is associated with the naming of the Ganga, while Prayagraj is a later confluence of major rivers. Memory cue: Devprayag means “Ganga begins by name.”
