The concept of ensuring that all people have access to sufficient, safe, and nutritious food:

Food safety
Food sovereignty
Food security
Food processing

The correct answer is C) Food security.

Food security is a condition in which all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food to meet their dietary needs and food preferences for an active and healthy life.

Food safety is the assurance that food will not cause harm to the consumer when it is prepared and/or eaten according to its intended use.

Food sovereignty is the right of peoples to define their own food and agriculture systems, based on their own priorities, needs, and aspirations, free from any form of external manipulation or control.

Food processing is the transformation of raw materials into food products that are safe, nutritious, and convenient for consumers.

Food security is a complex issue that is affected by a variety of factors, including climate change, conflict, economic instability, and population growth. There is no one-size-fits-all solution to food security, but there are a number of things that can be done to improve food security around the world, such as increasing agricultural productivity, improving access to markets, and investing in social protection programs.
