Explanation

When configuring EtherChannel on Cisco devices, the relevant modes alongside LACP are on (A) and passive (B). Passive is a true LACP mode where the port waits for an LACP PDU from the remote side before forming the bundle (it responds but does not initiate). On forces the EtherChannel to form statically without any negotiation protocol - no LACP PDUs are sent or expected. The complementary LACP negotiation mode is active (initiates LACP), but it is not among the answer choices. 'Associated' and 'link' are not valid EtherChannel modes.
