At which Harappan settlement, the sections within the lower towns were separated by walls?

Lothal

The correct answer is Option 3 - Lothal

While most Harappan settlements have a small high western part and a larger lower eastern section, there are variations. At sites such as Dholavira and Lothal (Gujarat), the entire settlement was fortified, and sections within the town were also separated by walls. The Citadel within Lothal was not walled off, but was built at a height.
