This question is like a VLAN tag team match! I'm betting on B to pin the other options and win the championship.

Hmm, this is a tricky one. I'm torn between B and D, but I'll go with B since it seems more logical to keep the FCS.

I'm going with C. Keeping the VLAN tag while removing the FCS sounds like the right way to handle a tagged frame on a null SAP.

D sounds good to me. Removing both the FCS and the VLAN tag seems like the most straightforward approach for a null SAP.

Hmm, I see your point. But I still think A makes more sense because keeping the VLAN tag would maintain the network segmentation.
