Give the freaking OE please!!
Let me try and give my explanation for this one.
First let us identify what the question is asking. At its simplest , it is asking for a supporting evidence ( of event) to confirm analyst's finding. Now what was the analyst finding - it was that the profit was a fluke/flash in a pan/not something which might happen again on a sustainable basis.
Now analysing the options
a) RBI appointed a new chairman / MD for the bank -- Agree that this will not happen every year so the once off profit could be attributed to the initial euphoria of a new head honcho but still not 100% conclusive. Will keep it in contention.
b) high profile business trips , old customers leaving the bank -- This , if not anything is contrary to the fact that there would have been profits . so out right rejected.
c) Release of funds - Some funds which were wrongfully taken from the bank in past were released this year thereby contributing to its bottom line. Looks like a very strong contender to support the claim of analyst that this won't happen evey year .
d) Film funding -- Starts on a good note but the bombing of the films is contrary to the fact that banks had a profit this year.
e) Old chairman elevated to Deputy governor -- Like a this is a once off event which potentially could cause the bank to show temporary profits , for eg - stocks of the bank rising in values because of investors speculating that the new deputy governor might issue policies in support of his old org.
Now we see that a, c and e are the possible candidates to explain the analyst's paradoxical thoughts. Out of these 3 , only c is conclusive , fact ridden so I would choose c. A and E are giving vague indicators and need to be supplemented by extra assumptions to explain the profit of the bank.
Hope this helps
