Which city is regarded as the largest of the Indus Valley civilization, indicating central planning?

Mohenjo-Daro is recognized as one of the largest urban centers of the Indus Valley civilization and serves as a prime example of advanced urban planning and design that characterized this ancient culture. The city features a sophisticated layout with a grid-like pattern of streets, ensuring efficient movement and organization within the settlement.

Key elements of central planning in Mohenjo-Daro include well-constructed drainage systems, public baths, and standardized fired-brick buildings, which exemplify a high degree of urban organization and engineering prowess. The presence of a citadel suggests a hierarchical structure in governance and society, reinforcing the idea of central planning and control over urban development.

In contrast, Harappa, while also significant within the Indus Valley civilization, is not quite as large or as prominently recognized for its urban planning features as Mohenjo-Daro. Memphis and Thebes, both located in Egypt, are unrelated to the Indus Valley civilization and therefore do not pertain to the question regarding central planning in that historical context.
