Option (A) is correct because these points align with the arguments in favour of power sharing provided in the text. The text states that power sharing helps to reduce the possibility of conflict between social groups (A) and prevents the tyranny of the majority, which implies it decreases the possibility of arbitrariness (B). It also mentions that in a democracy, due respect is given to diverse groups (D) and that political power should be distributed among citizens to promote people's participation (F). Statements C, E, and G are arguments against power sharing or outcomes of not sharing power (e.g., imposing majority will undermines unity).
