Which configuration example accomplishes this?

You want to configure per-flow equal-cost multipath (ECMP) load balancing for only the OSPF routes on Router-1. Which configuration example accomplishes this?

A.
protocols {
ospf {
export EMCP;
}
}
policy-options {
policy-statement ECMP {
term first {
from protocol ospf;
then {
load-balance per-packet;
}
}
}
}

B.
routing-options {
export ECMP;
}
policy-options {
policy-statement ECMP {
term first {
from protocol ospf;
then {
load-balance per-packet;
}
}
}
}

C.
routing-options {
forwarding-table {
export ECMP;
}
}
policy-options {
policy-statement ECMP {
term first {
from protocol ospf;
then {
load-balance per-packet;
}
}
}
}

D.
routing-options {
forwarding-table {
export ECMP;
}
}
policy-options {
policy-statement ECMP {
term first {
from protocol ospf;
then {
load-balance ECMP;
}
}
}
}
