B. Lord Canning
C. Cyril Radcliffe
D. Stafford Cripps

Complete answer:
Lord Curzon- Curzon Line, the demarcation line between Poland and Soviet Russia that was proposed as a potential armistice line during the Russo-Polish War of 1919-20 and became the Soviet-Polish frontier after World War II (with a few modifications).
Lord Canning- From 1856 to 1862, Lord Canning served as India's Governor General. The Government of India Act, 1858, was passed during his term, which established the office of Viceroy to be held by the same person who was Governor General of India. Thus, Lord Canning also acted as India's first Viceroy.
Cyril Radcliffe- The border commission that formed the border between India and Pakistan was led by Sir Cyril Radcliffe. It was quite an arbitrary line, according to historian Ayesha Jalal,' which in some instances split villages into two'.
Stafford Cripps- Sir Richard Stafford Cripps was a politician, barrister, and diplomat for the British Labor Party. Before 1939, after he was excluded from the Labor Party, he became a leading spokesperson for the left-wing and for unity in the Popular Front with the Communists.
