After the packet arrives at PE2, PE2 distributes label 1025 to the packet. When a client on PE2 accesses this route, what are the outer and inner labels in the packet transmitted over the carrier network?
A. Outer label: 1027; inner label: 1025
B. Outer label: 1025; inner label: 1025
C. Outer label: 1027; inner label: 1027
D. Outer label: 1025; inner label: 1027
