Manasarovar Lake, situated in the Himalayas, is the source of three major rivers: the Brahmaputra, the Indus, and the Sutlej.
These rivers originate in this region, which is part of the Tibetan Plateau, and flow through various regions of the Indian subcontinent.
The Krishna, Godavari, and Penna rivers, listed in Option (1), do not originate near Manasarovar.
Similarly, Yamuna, listed in Option (4), does not originate from the Himalayas, and the Jhelum is not associated with the Sutlej.
Hence, the correct answer is Brahmaputra, Indus, and Sutlej.
