Explanation:

Oily or gas - soaked rags are flammable. Leaving them on a bench (option a) or in a plastic bag (option b) or a sealed plastic container (option c) can be dangerous as they can ignite. Storing them in a steel container with an air - tight lid (option d) is the safest way as steel is non - flammable and the air - tight lid reduces the risk of ignition by limiting oxygen and preventing the spread of fumes.

Answer:

d. Stored in a steel container with an air tight lid
