The important ports in the Mauryan period were Tamralipti on the east coast and — on the west

This question examines a key feature of Mauryan political history, administration, economy, art, religion, or epigraphy. The correct answer is Bhrigukachchha and Sopara. Tamralipti served eastern maritime routes, while Bhrigukachchha and Sopara were important western ports. Muziris, Arikamedu and Kaveripattinam are better known in later peninsular trade, and Lothal belongs to the Harappan age. A strong answer should connect the term or object with its precise source, location, ruler, regnal context, and administrative function.
