The Simon Commission, formally known as the Indian Statutory Commission, was appointed by the British government in November 1927 to review the political situation and constitutional reforms in British India. It arrived in India in early 1928. The options given (1925, 1926, 1927, None of these) do not include the exact appointment year 1927 as a standalone correct choice because the commission was appointed specifically in November 1927, which is late in the year, and the arrival and activity mainly took place in 1928. Therefore, the best answer among the given options is 'None of these' since the commission was appointed in late 1927 and arrived in 1928, not exactly in 1925, 1926, or early 1927.
