Solution:Smuggler is the correct word.A smuggler is someone who unlawfully transports goods and people into or out of a country. For example, "drug smugglers." As a result, Option 3 is right. Among the other options, exporter refers to a person, country, or company that sends goods or services to another country for sale, importer refers to a person or organisation that brings goods or services into a country from another country for sale, and imposter refers to a person who pretends to be someone else in order to deceive others, particularly for fraudulent gain. These are incorrect because they do not express the original meaning.
