Banawali in Haryana provides evidence of which agricultural implement?

Banawali in Haryana yielded a terracotta model of a plough, providing evidence related to Harappan agriculture. It is not the site of the Great Bath, a dockyard or Dholavira’s monumental stone reservoirs. Thus the other options either belong to a different archaeological site, represent a different period, or do not match the specific evidence asked in the question. The evidence must connect patronage, place and historical period simultaneously. A terracotta model of a plough fits that evidence because it matches the specific chronology, agency and function contained in the question. A comparison with the alternatives is useful: A dockyard, The Great Bath and A stone reservoir are genuine historical terms or names, but each belongs to a different office, patron, text, region or sequence. The compact memory link is therefore A terracotta model of a plough together with the factual context above, not the isolated option letter.
