Which of the following statements best describes the term 'Scheme for Sustainable Structuring of Stressed Assets (S4A)', recently seen in the news?

1. A

   It is a procedure for considering ecological costs of developmental schemes formulated by the Government.

   This option reads S4A as an ecological-cost appraisal of government schemes. Sustainable Structuring of Stressed Assets is a banking resolution tool, not an environmental clearance procedure. This option is not the key.

2. B

   It is a scheme of RBI for reworking the financial structure of big corporate entities facing genuine difficulties.

   S4A was an RBI scheme (2016) to rework the financial structure of large stressed corporate accounts facing genuine difficulty, by separating sustainable and unsustainable debt. That description is the official key.

3. C

   It is a disinvestment plan of the Government regarding Central Public Sector Undertakings.

   Disinvestment of CPSUs is a Department of Investment and Public Asset Management agenda, not S4A. This option is therefore wrong.

4. D

   It is an important provision in 'The Insolvency and Bankruptcy Code' recently implemented by the Government.

   The Insolvency and Bankruptcy Code is a later, separate statutory insolvency process. S4A was an RBI prudential scheme, not a clause of IBC. This option is not the key.

Summary. Official key is (b). S4A (Scheme for Sustainable Structuring of Stressed Assets) was the Reserve Bank’s 2016 tool for large corporate stressed loans. It allowed a sustainable debt to be serviced and the rest to be converted or recast. It is not an ecology test, not a disinvestment plan, and not a provision of the IBC. Only (b) matches the banking meaning.
