Which configuration must the operator use to remedy this failure scenario?

A service provider engineer enabled the BGP next-hop tracking feature and also tuned the OSPF to increase the network convergence in case of network failures. However, the operator engineer notices that in cases of PE failure, the network convergence is still slow.

Which configuration must the operator use to remedy this failure scenario?
A . router bgp 65000
address-family ipv4
bgp nexthop trigger delay 1
!
address-family vpnv4
bgp nexthop trigger delay 1
B . ip prefix-list PREFIX_32 permit 0.0.0.0/0 ge 32
!
route-map ONLY_32 permit 10
match ip address prefix-list PREFIX_32
match source-protocol ospf
!
router bgp 65000
address-family vpnv4
bgp next-hop route-map ONLY_32
C . router ospf 1
default-information originate always metric-type 1
timers throttle Isa 1 5 5000
timers throttle spf 1 5 5000
D . router ospf 1
no default-information originate
tiers throttle Isa all 1 5 5000
times throttle spf 1 5 5000
E . router bgp 65000
address-family ipv4
no bgp next-hop trigger enable
bgp additional-paths install
!
address-family vpnv4
no bgp next-hop trigger enable
bgp additional-paths install
