What urban feature demonstrates the Indus Valley’s advanced planning?

• A. Pyramids and temples
• B. Stone roads
• C. Caravansaries
• D. Consistent brick sizes and sophisticated drainage networks

Answer: (D)

The key idea here is how the Indus Valley cities were planned and managed for daily life. What stands out about their urban design is the combination of uniform building materials and a citywide drainage system. The bricks used across major sites were standardized in size, which shows coordinated engineering and consistent construction practices across neighborhoods and even different cities. This kind of standardization isn’t just about individual buildings; it reflects a coordinated approach to masonry and urban infrastructure.

Alongside that, there was a sophisticated drainage network: brick-lined drains running under streets, carrying wastewater away from homes and public spaces, with outlets and maintenance access points. This shows deliberate municipal planning aimed at sanitation, order, and public health, not just isolated architecture. The ability to design and maintain such a system across a city points to advanced planning and social organization.

Other options point to features more typical of different civilizations or later periods. Monumental pyramids and temples are strongly associated with Egypt and Mesopotamia rather than the Indus Valley. Caravansaries relate to later trade networks along land routes, and while trade existed, the standout indicator of Indus urban planning is indeed the standardized bricks and the drainage network.
