Explanation

Statement I: is correct Activated carbon is widely used for removing pollutants and remediating industrial contaminants — this is true and widely supported in environmental and chemical engineering fields. • Statement II is correct: Activated carbon indeed has a very large surface area and strong adsorption capacity, especially for heavy metals and organic pollutants — this explains why it’s effective in pollution control (i.e., supports Statement I). • Statement III is correct: Activated carbon can be synthesized from a variety of carbon-rich environmental wastes like coconut shells, sawdust, and agricultural residues — this is also true and relates to its accessibility and environmental sustainability, contributing to its attractiveness mentioned in Statement I.
