The correct options are
A The Partiton worsened the religious conflict between Muslims and Hindus
B The Partition allowed the introduction of new administrative policies favouring the British.
D The Partition clamped down on the growing wave of nationalism in Bengal
The Partition of Bengal favoured the British. This partition, ostensibly carried out for administrative purposes, allowed the British to manipulate religious tensions between the Muslims and Hindus, giving the British the leeway to exert their dominance. It also allowed them to extend their power through newer policies, and dampened the nationalist spirit. However, the Anti-Partition and Swadeshi movements negatively impacted the sale of British goods in the subcontinent since Indians were boycotting foreign products.
