Didn't get it. Can anyone explain?

Why not B option?

Option A is right because in the sentence we are giving the past time, so they must be past indefinite.

Option B is not allowed because subject other countries are given so.

I think it can be B.

I think it can be D as the incident has happened long ago.

Why not option B?

It can't be option B?

Because past perfect tense is only used when we are talking about two past actions (no other case used).

Eg: When I reached the station, the train had already left.

Past perfect tense tells which action is done first in the two past actions.
