The correct option is (a).
Explanation
Lothal, located in the Bhal region of Gujarat, was a vital port city and industrial centre of the Indus Valley Civilization. It is archaeologically significant for its maritime architecture and specialized craft production.
Statement-wise Analysis:
- Statement 1 is Correct: Lothal was a highly organized industrial centre. Excavations have revealed workshops for bead-making (particularly carnelian), shell-working, and copper-smithing. It was a primary source for objects made of stone, shell, and metal, which were traded extensively.
- Statement 2 is Incorrect: The massive trapezoidal brick tank found at Lothal is identified as a dockyard. It was connected to the river Bhogavo by a channel, facilitating the movement of ships for trade. The structure famously associated with ritual bathing or a pool is the Great Bath at Mohenjo-daro.
- Statement 3 is Incorrect: A prominent structure identified as a warehouse (storehouse) was discovered at Lothal close to the acropolis. Inside this structure, numerous clay sealings (impressions of seals on packed goods) were found, which serve as evidence of administrative control over trade and storage.
Key Takeaway:
Lothal is distinguished by the world's earliest known artificial dockyard and a warehouse containing clay sealings, confirming its role as a major hub for maritime trade and craft manufacturing.
