Correct Answer: Dockyard

Solution : The correct answer is Dockyard.

Lothal, located in Gujarat near the Gulf of Khambhat, is believed to have one of the world's earliest dockyards. Its urban planning was precise, featuring lota-shaped bathrooms and containers, emphasising cleanliness. The city's grid layout, well-maintained roads, and effective drainage systems showcased exceptional civic design. Some Lothal seals suggest an upper and lower town division. The durability of carnelian beads attests to bead-makers' skill in ancient Lothal.
