Answer

Yamuna is a major right-bank tributary of the Ganga river system.
Yamuna is the longest and major right-bank tributary of the Ganga. It originates from the Yamunotri Glacier on the Banderpoonch peak in the Garhwal region and merges with the Ganga on its right bank at Prayagraj.

Step-by-Step Solution

1
Identify the orientation of tributaries joining the Ganga River.
Tributaries joining from the south (right bank) include Yamuna, Son, and Punpun. Tributaries joining from the north (left bank) include Ramganga, Gomti, Ghaghara, Gandak, Kosi, and Mahananda.
Categorizing tributaries by their bank alignment helps distinguish left-bank from right-bank rivers.
2
Evaluate the given options based on their confluence alignment.
Yamuna joins the Ganga on its right bank at Prayagraj, while Gomti, Ghaghara, and Gandak join from the left bank.
Yamuna flows parallel to the Ganga along its right side before merging at Triveni Sangam.
