A notable feature of Indus cities?

• A. Advanced drainage systems
• B. Monumental pyramids
• C. Dense forest cover
• D. Underground metro

Answer: (A)

Indus cities stand out for their sophisticated urban infrastructure and sanitation. Excavations at sites like Mohenjo-daro and Harappa show grid-like street layouts and a extensive drainage network. Narrow brick-lined drains ran along the roads and connected to individual houses, carrying wastewater away from living spaces and toward larger outlets that led to rivers or to dumps. This emphasis on organized sewage systems and public hygiene reflects a highly planned approach to city life, making advanced drainage systems the defining feature.

Monumental pyramids are traits of other ancient civilizations, not the Indus Valley. Dense forest cover isn’t what these cities are known for; their remains point to dense settlements built with fired bricks rather than surrounding forests. An underground metro is a modern concept with no basis in these ancient urban landscapes.
