Referring to the exhibit, how should an export policy be configured to export only the 50.50.1.0/24
RIP summary route into OSPF?

A.
[edit policy-options policy-statement RIP-redist]
user@router# show
term 1 {
from {
protocol rip;
route-filter 50.50.1.0/24 exact;
}
then accept;
}
term 2 {
from {
protocol rip;
route-filter 50.50.0.0/24 upto /27;
}
then reject;
}
term 3 {
from protocol rip;
then accept;
}

B.
[edit policy-options policy-statement RIP-redist]
user@router# show
term 1 {
from {
protocol rip;
route-filter 50.50.0.0/24 upto /27;
}
then reject;
}
term 2 {
from {
protocol rip;
route-filter 50.50.1.0/24 exact;
}
then accept;
}
term 3 {
from protocol rip;
then accept;
}

C.
[edit policy-options policy-statement RIP-redist]
user@router# show
term 1 {
from {
protocol rip;
route-filter 50.50.0.0/16 prefix-length-range /24-/26;
}
then reject;
}
term 2 {
from {
protocol rip;
route-filter 50.50.1.0/24 exact;
}
then accept;
}

D.
[edit policy-options policy-statement RIP-redist]
user@router# show
term 1 {
from {
protocol rip;
route-filter 50.50.1.0/24 exact;
}
then accept;
}
term 2 {
from {
protocol rip;
route-filter 50.50.0.0/16 prefix-length-range /24-/26;
