B is just about forwarding decisions, not really a control plane function. I'm going with C as the best option here.

Ha! Imagine if the answer was A - de-encapsulating and re-encapsulating a packet. That would be more of a data plane task, not control plane.

I think D is also a good answer. The Neighbor Discovery Protocol is definitely part of the control plane in IPv6 networks.

Option C seems to be the correct answer here. Matching the destination IP address to the routing table is a classic control plane action.

I disagree, I believe it is A) de-encapsulating and re-encapsulating a packet in a data-link frame.

I think a control plane action is C) matching the destination IP address of an IP packet to the IP routing table.
