The main goal of Codex Alimentarius is to:

The main goal of the Codex Alimentarius is to establish international standards for food safety. This is primarily achieved through the development of guidelines and codes of practice that help ensure food is safe for consumers, fair in trade practices, and can be consumed without posing a health risk. By providing these standards, Codex helps countries harmonize their food safety regulations and facilitates international trade by ensuring that food products meet the required criteria for safety and quality.

While the other options touch on important aspects of food and agricultural policies, they do not directly align with the core mission of Codex. Increasing agricultural production pertains more to agricultural practices and policies rather than food safety standards. Promoting food trade regulations relates to economic aspects and trade agreements that may incorporate food safety but are more broader than what Codex specifically focuses on. Reducing global hunger, while a critical global challenge, is more about access to food and socio-economic factors rather than the establishment of safety standards that Codex specifically aims to address. Thus, the emphasis of Codex on food safety standards places it squarely within the context of consumer protection and international food trade.
