Explanation

An access port is assigned to exactly one VLAN and carries only untagged traffic for that VLAN, making it the only port type inherently restricted to a single VLAN membership. Trunk ports (C) are designed to carry tagged traffic for multiple VLANs simultaneously across switch-to-switch or switch-to-router links, so they belong to many VLANs. Hybrid ports (B), a port mode common on Huawei devices, can handle both tagged and untagged traffic for multiple VLANs at once, disqualifying them as well. An eth-trunk (D) is a link aggregation group that bundles multiple physical interfaces into one logical link for redundancy and bandwidth; it is not a VLAN membership type and can itself be configured as access, trunk, or hybrid, so it is not inherently limited to one VLAN.

Memory tip: Access = one address. Just as a home's street address points to one specific house, an access port points to exactly one VLAN.
