Gateway drugs are substances that people may start with and that can set the stage for trying more powerful, more addictive drugs later. Early use can influence brain reward pathways, increase tolerance, and bring individuals into social situations where harder drugs are present, raising the likelihood of experimenting with them. That progression is why the best description is that gateway drugs can lead to other stronger, more addictive drugs. The other options don’t fit because they don’t describe this progression to harder drugs: legal medicines aren’t the typically implied next step, non-addictive supplements aren’t linked to addiction, and recreational activities aren’t drugs.
