Explanation:

• Statement 1 is incorrect. The Anna Chakra initiative is not focused on monitoring food quality. Instead, it is a supply chain optimization tool aimed at improving the efficiency of foodgrain movement in the Public Distribution System (PDS). It uses advanced algorithms to optimize routes, reduce costs, and enhance logistics efficiency, covering Fair Price Shops and warehouses. 

• Statements 2 and 3 are correct. The SCAN portal is designed to provide a single-window system for states to submit subsidy claims under the National Food Security Act (NFSA). It automates the workflow for claim submission, scrutiny, and approval, ensuring faster and more transparent settlement of food subsidies. Both initiatives are linked to the implementation of the NFSA, which aims to provide subsidized foodgrains to eligible beneficiaries. Anna Chakra enhances PDS logistics under the NFSA, while SCAN streamlines subsidy claims processes related to the Act. 

Hence option 2nd is correct.
