Various Himalayan and Indian geological features have well-established stratigraphic/tectonic associations: fluvio-glacial Neogene rocks with the Himalayan foreland basin (Siwalik-type deposits), the Precambrian-Cambrian boundary with the Krol basin succession, the Permian-Triassic boundary with the Tethyan basin sequences, and the K-T boundary with the intertrappean beds of the Deccan Traps.
The correct matches are: fluvio-glacial Neogene rocks - Himalayan Foreland basin (i-b); Precambrian-Cambrian boundary - Krol basin (ii-c); Permian-Triassic boundary - Tethyan basin (iii-d); K-T...
