Which metal was used to make the script-seal with 'R.H-37' peg?
Explanation
, excavator, or cultural practice referred to in the stem.
Option-wise analysis: Harappa is correct because it fulfils the precise historical condition asked. Mohenjodaro is incorrect because it belongs to a different site, discovery, period, location, or cultural association. Chanhudaro may be connected with ancient Indian history, but its defining evidence does not match this question. Kalibanga is also incorrect because the site–feature, person–excavation, river–settlement, or chronology link is different.
For examination purposes, classify the question before selecting an answer. If it asks about a site, recall its location, river, excavator, and special discovery. If it concerns an artefact, distinguish the place where it was found from the material or interpretation attached to it. If it concerns dates, separate Early, Mature, and Late Harappan phases. Archaeological interpretations may change when new evidence appears, so use the standard association accepted in school texts and competitive examinations. Therefore option A, Harappa, matches the marked correct index and is the best-supported answer.The R.H-37 artifact tag refers to excavation finds from Harappa (R.H = Rakhal Harappa or Rai Harappa excavation reference). The famous cemetery R-37 at Harappa yielded important burial evidence about the Harappan people. This is a specialized UPSC-level question.
