The correct option is D Blockaded ships with the Company's goods
The East India Company tried to interfere in internal politics by backing Siraj-ud-Daulah's rival's claim to Bengal's leadership. On top of this, the Company was stockpiling weapons and refused to pay tributes or taxes. Siraj Ud Daulah marched with 30,000 soldiers to the factory at Kasimbazar. The Company's employees were held hostage by the Nawab. He locked their warehouse, took away their weapons, and blockaded their ships.
