Among the options provided, the correct answer is establishing safety standards for products.
Economic regulation pertains to rules and guidelines that control economic activities, ensuring fair competition and consumer protection. Establishing safety standards for products falls into this category as it directly relates to the market by setting standards that manufacturers must meet to ensure that their products are safe for consumer use.
On the other hand, regulating air and water pollution and protecting workers are examples of social regulation. These focus on societal welfare and protecting public interest rather than directly manipulating the economic framework. Social regulations tend to deal with issues that affect public health and safety but do not necessarily form part of the economic structure.
