Answer: (b)

Explanation:
The Food and Agriculture Organization promotes the concept of "Blue Transformation" to ensure sustainable use of aquatic food systems, especially fisheries and aquaculture. A central framework within this initiative is the "Four Betters", which aligns with FAO's broader goal of achieving sustainable development in food systems.

These Four Betters are:
Better production (sustainable and efficient aquatic food systems)
Better nutrition (healthy and accessible aquatic foods)
Better environment (ecosystem protection and sustainability)
Better life (improved livelihoods and social well-being)

This framework extends the idea of "Four Betters" already used in FAO's overall transformation agenda and adapts it to oceans and aquatic systems under Blue Transformation.

Therefore, the correct answer is (b).
