​​Who was the first Indian who entered as a law member into the Viceroy's Executive Council?

Correct option is D

Satyendra Prasanna Sinha, popularly known as S.P. Sinha, was the first Indian to be appointed as a law member of the Viceroy's Executive Council in 1909 and later the first Indian to become a Governor (Governor of Bihar and Orissa in 1920). He also represented India at the Versailles Peace Conference in 1919. This appointment marked a significant moment in the constitutional development of British India, as it showed a shift towards limited inclusion of Indians in high governmental offices under British rule. His appointment was associated with the reforms initiated by the Morley-Minto reforms (Indian Councils Act, 1909) that aimed to increase Indian participation in governance, though still under strong British oversight. Sinha’s legal background as a prominent barrister and his political engagements made him a natural choice for this position.
