Here are the reasons for the correct statements:

(A) Nawab Wajid Ali Shah was deposed from Awadh: Nawab Wajid Ali Shah, the ruler of Awadh (Oudh), was deposed by the British during the course of the Revolt of 1857. The British accused him of being involved in the rebellion and subsequently exiled him.

(B) Mutiny started from Delhi: The Revolt of 1857 is often considered to have started with the mutiny of Indian soldiers in the British East India Company's Bengal Army, which began in Meerut and then spread to Delhi. Delhi became one of the early centers of the rebellion, making it an important starting point for the uprising.

The other options (C), (D), and (E) are not accurate in the context of the Revolt of 1857.

So, the correct option is [1].
