The part of the Himalayas lying between Satluj and Kali rivers is known as…

Concept — The Himalaya is divided regionally, from west to east, into four river-bounded sections. The boundary between any two neighbouring sections is a major river that cuts transversely across the range, and each section takes its name from the territory it traverses. Naming a section therefore means locating the two rivers that bound it.

Application — The stem fixes both bounding rivers: the Satluj on the west and the Kali on the east. Reading the scheme from west to east, the first section runs from the Indus to the Satluj. The section that begins where the Satluj cuts the range and ends where the Kali cuts it is the Kumaon Himalaya, the mountain belt of present-day Himachal Pradesh and Uttarakhand.

Cross-check — the four regional divisions with their bounding rivers:

• The Nepal Himalaya begins only where the Kali cuts the range and runs east to the Teesta, one segment further east than the belt asked about.

• The Assam Himalaya lies east of the Teesta and ends at the Dihang gorge of the Brahmaputra, two segments further east.

• Every west-to-east segment in this scheme carries a single regional name, and the name of the Satluj-to-Kali segment is present among the given choices.

Answer: Kumaon Himalayas. Many texts write it as the Kumaon-Garhwal Himalaya, since Garhwal and Kumaon together make up this belt.
