The Centralized Laboratory Network (CLN) is a global network of advanced labs that allows member countries to perform rapid and standardized testing on critical substances.
India joined CLN with the objective of enhancing its capabilities in monitoring and testing food adulteration and food safety.
This step was taken due to increasing concerns over food quality and the rising cases of adulteration, particularly in urban and semi-urban areas.
CLN enables access to best practices, equipment, protocols, and data sharing among member laboratories across different nations.
Contrary to popular misunderstanding, CLN is not directly related to nuclear weapon testing or vaccines—it primarily focuses on consumer safety in food and health products.
Thus, the correct answer is (A) Adulteration in food.
