The question tests the precise composition of a Bar Council Disciplinary Committee as fixed by Section 9(1) of the Advocates Act, 1961. Each option proposes a different headcount and a different method of constituting the committee, so the analysis has to check both against each other.
Only the option with two elected members and one outside co-opted advocate keeps both the number of members and the elected-versus-co-opted split exactly as Section 9(1) lays it down.
Therefore, the correct answer is Three members, two elected from the Council's membership and one co-opted advocate possessing the prescribed qualifications, who is not a member of the Council.
