The answers are badly worded. Most probably, it is about a unique vlan id for the native vlan (different from the default vlan 1) https://www.ciscopress.com/articles/article.asp?p=1681033&seqNum=3 https://learningnetwork.cisco.com/s/blogs/a0D3i000002SKPREA4/vlan1-and-vlan-hopping-attack https://learningnetwork.cisco.com/s/question/0D53i00000KssdaCAB/native-vlan-tagging Some chances are that they meant the native vlan tagging.

Adding native in front of vlan in option A makes a lot of sense.
