B is a very tempting choice. But it is not the right answer for the question.

Any official who takes bribes is filthy rich. No official who was under surveillance by National Security Bureau takes bribes. Therefore, any official who was under surveillance by National Security Bureau is good to have.

Premise:
1) Official takes bribes --> filthy rich
2) Offical tracked by NSB --> takes no bribes

Conclusion:
Official tracked by NSB --> good to have

One way to find the assumption of an arugment is to "stretch" the conclusion and then plug in the the known premise accordingly:
Official tracked by NSB --> ?? --> good to have
Offical tracked by NSB -->[ takes no bribes] --> good to have
Then the assumption is: takes no bribes --> good to have !! Answer choice E puts this assumption into GMAT words.
