What was dangerous for the British Empire?

The correct answer is (A) Communal unity and national spirit.

• Logical Principle: The British colonial policy in India was fundamentally based on the 'Divide and Rule' strategy, which relied on exploiting communal, regional, and social divisions to maintain their hegemony. Therefore, any cohesive force acting against this fragmentation posed a direct threat to the stability of the British Empire.
• Step-by-Step Deduction: British administrative control depended heavily on preventing a unified nationalist front. Communal unity eliminates the fault lines that colonial powers exploit, while the national spirit fosters a collective consciousness of resistance against foreign oppression. Together, they form the bedrock of an anti-imperialist mass movement.
• Verification and Option Contrast: Option (A) directly threatens British rule as unity and nationalism mobilize the entire populace. Conversely, options (B) 'Sense of animosity', (C) 'Sense of division', and (D) 'Sense of bitterness' actually aided the British colonial agenda by keeping Indians fractured and mutually distrustful, making them incorrect choices.
