This is a trick question. The key is the location it is being applied. Since they present two options, one is clearly not on the interface, and the other could mean literally on the interface, the answer is D. A traffic control profile is not applied literally on the interface at the interface level. The answer is not A because input-shape-rate is not a command.

Should be D if C means TCP applies under interface level.

It is D: [edit class-of-service] interfaces { xe-4/0/0 { shaping-rate 5g; } }

Anyone has idea in between C and D ? In fact, both Traffic Control Profile (TCP) and Shaping-rate under physical interface are able to achieve this goal. Only difference are TCP can be under if-set , logical interface but D is only for physical interface.

BTW, if C means apply it to all interfaces "under interface hierarchy", then it definitely wrong. D is under correct configuration hierarchy.
