Explanation:

•  Islington Commission, 1912 a Royal Commission formed to recommend reforms in the Public Service of British India with Lord Islington as its chairman. A ten member commission, which included three Indians. Hence pair 1 is correctly matched. 
• Islington Commission was given the task of examining the Indian demand to increase the number of Indians in the Higher Civil Services and, most importantly, holding simultaneous examination in India.
• The commission was guided by three principal considerations: firstly, to maintain high standards of civil administration in British India; secondly, to safeguard the paramount interest of British rule; and thirdly, to satisfy the reasonable aspirations of Indians and promote friendly relations between Indians and Europeans for better governance. The commission completed its report in 1915, but owing to the outbreak of the First World War, the report was not published until 1917.
• The recommendations of the report became defunct in 1918, when the montagu-chelmsford report proposed Indian appointment to one-third of the posts and action was taken in favour of holding simultaneous ISC examination in London and New Delhi in 1922. 
• Muddiman Committee, 1924 a committee appointed by the Government of India in early 1924 with the terms of reference of making an empirical investigation into the working of the Constitution as set up in 1921 under the India Act of 1919, and making appropriate recommendations for the consideration of the authorities. The immediate background to the committee was the mounting political unrest on the dyarchy issue of the Constitution. The official designation of the committee was the Reforms Enquiry Committee, but it came to be known as the Muddiman Committee after the name of its chairman, Sir Alexander Muddiman, who was then a Home Member of the Government of India. Hence pair 2 is not correctly matched.  
• Lee Commission, was appointed by the British government in 1923 to consider the ethnic composition of the superior Indian public services of the government of India. The chairman was Lord Lee of Fareham, and there were equal numbers of Indian and British members. The Lee Commission proposed in 1924 that 40 percent of future entrants should be British, 40 percent Indians directly recruited, and 20 percent Indians promoted from the provincial service. By the date of independence in 1947, more than half the service of about 1,000 members were Indians, many with long experience and holding high positions.
• In 1902, Raleigh Commission was set up to go into conditions and prospects of universities in India and to suggest measures for improvement in their constitution and working. The commission precluded from reporting on primary or secondary education. It is also known as the Indian Universities Commission of 1902, its major recommendations were the reform of school education, curricular reforms at universities, recommendations on education and examinations and state scholarships. Based on its recommendations, the Indian Universities Act was passed in 1904. Hence, pair 3 is not correctly matched.
