Correct Answer: C

TOS = Trunk Operational Status
TAS = Trunk Administrative Status
TNS = Trunk Negotiated Status
TOT = Trunk Operational Trunk-Encapsulation
TAT = Trunk Administrative Trunk-Encapsulation
TNT = Trunk Negotiated Trunk-Encapsulation

Operational = What we are doing at this moment
Administrative = How we configured it
Negotiated = What we asked for during the negotiation

If we look for trunk-encapsulation TAT, it's set for ISL. It will not work for .1q.
