During the revolt of 1857, also known as the Indian Rebellion of 1857 or the First War of Independence, several regions and groups rose in revolt against the British rule in India. Out of the options provided, the option 4 - Awadh Regiment is the correct answer.

The Awadh Regiment, which consisted of soldiers from the Awadh region (modern-day Uttar Pradesh), played a prominent role in the revolt of 1857. The Awadh region was particularly affected by British policies, including the annexation of the kingdom of Awadh in 1856. The British East India Company`s decision to annex Awadh led to widespread dissatisfaction among the Indian soldiers.

The Indian soldiers in the Awadh Regiment, along with other rebels, rose in revolt against the British in 1857. They were joined by various other regions and groups across India, including soldiers from the Bengal Army and civilians who were unhappy with British policies and their treatment.

It is important to note that while the Awadh Regiment played a significant role in the revolt, it was not the only group that revolted against the British. The rebellion was a widespread uprising that saw participation from various sections of society, including soldiers, peasants, and local leaders, across different regions of India.
