Step 2: Detailed Explanation:
- ISI Mark: This mark is mandatory for many products sold in India, especially items involving safety, such as electrical appliances, electronic goods, building materials like cement, and automotive components.
- Fruits, Vegetables, and Cereal: These are agricultural products and do not fall under the category of industrial goods that require ISI certification. They are more likely to have AGMARK.
- Iron: The term "Iron" here most likely refers to a clothes iron (an electrical appliance) or iron as an industrial material (like iron rods). Both an electric iron and industrial iron materials are required to have the ISI mark to ensure they meet safety and quality standards.
