Answer : 4. "ओईसीडी"
Explanation :

The most recent assessment on agricultural policy and support worldwide by the Organization for Economic Co-operation and Development (OECD) showed that in 2022, Indian farmers had to pay an implicit tax of $169 billion. This tax was the result of export restrictions, duties, or permits imposed on various commodities, including wheat and rice, in an effort to stabilize prices for consumers. As a result of these measures, the overall market price support (MPS) for farmers has become negative in 2022.
