The store-room in which the arms and ammunition were stored by the British authorities came to be known as:

Bell of Arms

The correct answer is Option (1) → Bell of Arms

The Bell of Arms was a storeroom in which weapons were kept by the British authorities.

The sepoys began their action with a signal: in many places, it was the firing of the evening gun or the sounding of the bugle. They first seized the bell of arms and plundered the treasury. They then attacked government buildings – the jail, treasury, telegraph office, record room, bungalows – burning all records. When ordinary people began joining the revolt, the targets of attack widened. In major towns like Lucknow, Kanpur, and Bareilly, moneylenders and the rich also became the objects of rebel wrath. Peasants not only saw them as oppressors but also as allies of the British.
