Which Commission accentuated the discontent in all the political groups and parties for not associating any Indian member in it?

Correct answer: (c) Simon Commission

Explanation

In 1927, the British government appointed a statutory commission to review the provisions of the Government of India Act, 1919; it was called the Simon Commission. All seven members of this commission were British, and not even a single Indian representative from any Indian political party, group, community, or organization was included in it.
