Which are valid modes for a switch port used as a VLAN trunk? (Choose three.)
This question is totally worded weird, be careful.
transparent is typically associated with a VTP mode and not an interface level
blocking and forwarding are STP and not necessarily the interface (aka per vlan STP)
auto/on/desirable are all three modes of enabling an ether channel, which can be a trunk port.
hence b/c/d are the most correct because the other three are wrong
