Correct answer: d.

The Indus (Harappan) urban civilization did not survive into the historic Gupta era and was not wiped out by Guptas or a 4th‑century tsunami. Its cities declined gradually (c. 1900–1300 BCE) due to factors such as weakening monsoons/climate change, river-course changes and flooding/drying, economic disruption, and population dispersal and assimilation. People moved into smaller villages and were absorbed into later South Asian populations — the collapse was complex, not a sudden mysterious disappearance.
