The correct answer is

Cartaz System

After Vasco da Gama reached Calicut in 1498, the Portuguese tried to dominate the sea trade of the Indian Ocean rather than conquer large territories.

Under the Cartaz system, every Asian or Arab merchant ship sailing in waters the Portuguese claimed had to buy a cartaz – a pass or licence – and often had to call at a Portuguese port and pay customs duty.

Ships found without a cartaz could be seized and their cargo confiscated, so this system gave the Portuguese control over maritime trade in the early 16th century.

The Subsidiary Alliance was introduced by Lord Wellesley in 1798 to bring Indian rulers under British control.

The Doctrine of Lapse was applied by Lord Dalhousie in the mid-19th century to annex states without a natural heir.

The Forward Policy refers to British efforts in the 19th century to extend control towards the North-West Frontier and Afghanistan.

Hence, the answer is Cartaz System.
