HI Ron,
I am confused between options B and E.
We have "had implemented", which is past perfect, so we need a past simple event. With this logic I chose B (tried).
Can you please explain what I am missing.

In this case, you appear to be trying to impose an alternate interpretation on the sentence that would make the answer choice incorrect. Keep in mind that if there are two possible interpretations of the sentence and one is grammatically correct while the other is not, you should ignore the incorrect interpretation and accept the correct interpretation..
