Which of the following is not a duty of an ombudsman?

Give binding decision

The correct answer is Option (3) → Give binding decision

An ombudsman typically investigates complaints, mediates disputes, and attempts to resolve issues, but their decisions are usually not binding. They provide recommendations for resolution, but they do not have the authority to enforce binding decisions like a court would.

"Whether appointed by a legislature, the executive, or an organization, the typical duties of an ombudsman are to investigate complaints and attempt to resolve them, usually through recommendations (binding or not) or mediation. Ombudsmen sometimes also aim to identify systemic issues leading to poor service or breaches of people's rights. At the national level, most ombudsmen have a wide mandate to deal with the entire public sector, and sometimes also elements of the private sector (for example, contracted service providers). Further redress depends on the laws of the country concerned, but this typically involves financial compensation"
