A.

On the local PE router, check that the routes from the local CE router are in the VRF table (routing-instance-name.inet.0):
user@host> show route table routing-instance-name.inet.0
The following example shows the routing table entries. Here, the loopback address of the CE router is 10.255.14.155/32 and the routing protocol between the PE and CE routers is BGP. The entry looks like any ordinary BGP announcement.
10.255.14.155/32 (1 entry, 1 announced)
*BGP Preference: 170/-101
Nexthop: 192.168.197.141 via fe-1/0/0.0, selected
State:
Peer AS: 1
Age: 45:46
Task: BGP_1.192.168.197.141+179
Announcement bits (2): 0-BGP.0.0.0.0+179 1-KRT
AS path: 1 I
Localpref: 100
Router ID: 10.255.14.155
If the routes from the local CE router are not present in the VRF routing table, check that the CE router is advertising routes to the PE router. If static routing is used between the CE and PE routers, make sure the proper static routes are configured.

so Answer D should be correct.
