The correct answer is B.
This is the catch! here.
user@router show policy-options
policy-statement send-direct {
term 1 {
from protocol direct;
then accept;
}
}
This policy statement will allow every directly connected interface with the following ip addresses, 10.0.0.0/24, 11.0.0.0/24 and 192.168.1.1/32

shobary was right, the correct answer is D.
A key point, and one that is often misunderstood and that can lead to problems, is that in such a configuration, only the most explicit policy is applied. A neighbor-level policy is more explicit than a group-level policy, which in turn is more explicit than a global policy.
The neighbor 192.168.1.2 is subjected only to the export send-static-100.0.20 policy. The neighbor 192.168.1.3, lacking anything more specific, is subjected only to the export send-static-100.0.0 policy. Meanwhile, neighbor 192.168.1.4 in group other-group has no group or neighbor-level policy, so it uses the Global policy export send-direct policy.
If you need to have neighbor 192.168.1.2 perform the function of all three policies, you can write and apply a new neighbor-level policy that encompasses the functions of the other three, or you can apply all three existing policies, as a chain, to neighbor 192.168.1.2
