The correct answer is C) Sakala.
Sakala is a citizen grievance redressal mechanism in Karnataka. It was launched in 2005 with the objective of providing a time-bound and hassle-free resolution of citizen grievances. Sakala has been successful in reducing the time taken to resolve grievances and has also improved the quality of service delivery.
Jan Sampark is a government initiative to improve communication between the government and citizens. It provides a platform for citizens to interact with the government and get their grievances resolved. Lok Adalat is a forum for resolving disputes between individuals or groups without going to court. Public Interest Litigation is a legal action that can be filed by any citizen to protect the public interest.
Sakala is a more appropriate answer to the question because it is specifically designed to address citizen grievances. Jan Sampark and Lok Adalat are also important initiatives, but they are not as focused on resolving citizen grievances. Public Interest Litigation is a powerful tool for protecting the public interest, but it is not a citizen grievance redressal mechanism.
