Step-by-step explanation:
You asked which one of the following is not one of the four pillars of food security: Availability, Access, Utilization, Stability, or Transformation. The correct answer to your question is Transformation. The four pillars of food security are indeed Availability (having sufficient quantities of food available on a consistent basis), Access (having sufficient resources to obtain appropriate foods for a nutritious diet), Utilization (appropriate use based on knowledge of basic nutrition and care, as well as adequate water and sanitation), and Stability (having a stable food supply without the risk of losing access to food as a consequence of sudden shocks or long-term stressors). Transformation is not considered one of the pillars of food security.
