In the description, I'm assuming by "get" it's supposed to be "gap"? As in "Don't gap your ground [return] plane, there's never really any reason to do that"
From Bogatin's _Signal Integrity Book_ [p.506]: 'We should remove the term _differential mode_ from our vocabulary and then we will never be confused between odd-mode impedance and differential impedance. They are completely different quantities. There are odd-mode impedances, differential signals, and differential impedances. [...] The odd-mode impedance is the impedance of one line when the pair is driven in the odd-mode state. The differential impedance is the impedance the differential signal sees as it propagates down the differential pair. [...] *There is no such thing as differential mode. Forget the word and you will never confuse differential impedance with odd-mode impedance.* ' So, in my opinion the correct answer is a.) Differential mode is not defined.

Todd is just a fantastic EMC design engineer. Thank you for this interview.

Yes, please invite him wink wink :-)
