The correct option is North and South.
Explanation
The Great Bath is one of the most distinctive and well-preserved structures located within the Citadel complex of Mohenjo-daro. It serves as a prime example of the engineering skills and ritualistic traditions of the Indus Valley Civilization.
Architectural Analysis:
- The structure comprises a large rectangular tank situated in a courtyard, surrounded by a corridor on all four sides.
- Access: There are two flights of steps on the north and south sides leading directly into the tank.
- Construction: The tank was made watertight by setting bricks on edge and using a mortar of gypsum. To prevent water seepage, a layer of natural tar (bitumen) was applied along the sides of the tank.
- Surroundings: Rooms were located on three sides of the bath. In one of these rooms, a large well was found, which likely supplied water to the tank. Used water was discharged through a huge drain.
Key Takeaway:
The Great Bath at Mohenjo-daro is characterized by flights of steps on the North and South, advanced waterproofing using bitumen, and its probable function for special ritual baths.
