What does food security mean?
Food security, as defined by the United Nations' Committee on World Food Security, means that all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their food preferences and dietary needs for an active and healthy life. Food security means availability, accessibility and affordability of food to all the citizens of the country at all times. The poor households are more vulnerable to food insecurity whenever there is a problem of production or distribution of food crops. Examples include soup kitchens, food banks, school lunch programs, and other programs that give food to people in need without requiring any type of commitment in return.
Hence, option ‘d’ is correct answer.
