Concept:A bonded warehouse is a secure government-approved facility where imported goods remain under official supervision until customs duties are paid.
Explanation:Imported goods entering a country are not immediately released into the open market.
They are placed in a bonded warehouse to defer the payment of import duties.
This warehouse is treated as a customs-controlled area, not as ordinary private storage.
The authority responsible for monitoring these warehouses is the customs and excise department.
Customs officers keep records of goods stored, verify documents, and ensure no goods leave without duty payment.
The warehouse is locked and supervised under customs laws.
Clearing agents merely help importers complete procedures; they do not supervise the warehouse.
Immigration officers handle people crossing borders, not goods.
Port authorities manage the physical port area, but they do not control customs-bonded storage.
Therefore, the supervision lies specifically with the customs and excise authorities.
Answer:D. customs and excise authorities
