The Harappan town planning of the lower town was designed in a particular pattern. What was the correct pattern of the town construction?

Approximate grid pattern

The correct answer is Option (2) → Approximate grid pattern

The Harappan settlement is divided into two sections, one smaller but higher and the other much larger but lower. Archaeologists designate these as the Citadel and the Lower Town respectively. The Citadel owes its height to the fact that buildings were constructed on mud brick platforms. It was walled, which meant that it was physically separated from the Lower Town.

Consider something else. Once the platforms were in place, all building activity within the city was restricted to a fixed area on the platforms. So it seems that the settlement was first planned and then implemented accordingly. Other signs of planning include bricks, which, whether sun-dried or baked, were of a standardised ratio, where the length and breadth were four times and twice the height respectively. Such bricks were used at all Harappan settlements. One of the most distinctive features of Harappan cities was the carefully planned drainage system. If you look at the plan of the Lower Town you will notice that roads and streets were laid out along an approximate “grid” pattern, intersecting at right angles. It seems that streets with drains were laid out first and then houses built along them. If domestic waste water had to flow into the street drains, every house needed to have at least one wall along a street.
