Detailed Solution:
The correct answer is “All the three above.”.
At the time, there was no unified sense of nationalism across the diverse Indian subcontinent, which made coordinated resistance against the British difficult.
The East India Company had access to advanced military technology and training, which gave them a significant advantage over many Indian forces.
Many Indian soldiers, such as those in the Company's army, were motivated by pay rather than national loyalty, which made it easier for the British to recruit and maintain a loyal army.
