Step 1: Recall major Indus Valley sites.
The Indus Valley Civilization had many urban centers, each known for specific features:
- Harappa: Granaries, fortifications, craft production.
- Mohenjo-Daro: Great Bath, advanced drainage system.
- Dholavira: Water reservoirs and signboard inscription.
- Lothal: Dockyard and bead-making industry.
Step 2: Analyze each option.
- (A) Banawali: Known for agricultural implements and terracotta toys, but no dockyard.
- (B) Shortughai: Located in Afghanistan, famous for lapis lazuli trade, not dockyard.
- (C) Lothal: Located in Gujarat, it had a well-planned dockyard connected to the Sabarmati River, proving maritime trade.
- (D) Chanhudaro: Known for bead-making and craft production, not dockyard.
Step 3: Conclusion.
The only Indus Valley site with clear evidence of a dockyard is Lothal, which highlights the maritime trade links of the civilization.
