As regards the use of international food safety standards as reference point for the dispute settlements, which one of the following does WTO collaborate with?

The WTO’s Agreement on the Application of Sanitary and Phytosanitary Measures (SPS) explicitly recognises the joint FAO/WHO Codex Alimentarius Commission as the international standard-setting body for food safety, and states that Codex standards, guidelines and recommendations serve as reference points for harmonizing measures and for WTO dispute settlement on food safety matters [1]. Official FAO/WHO Codex guidance and WTO documentation reinforce that members should base their sanitary or phytosanitary measures on Codex standards where they exist, and that Codex is the named relevant body in the SPS Agreement for food safety issues used in dispute resolution [2].
