Need your help here!

I feel B cannot be the answer for the following reason -
Let us assume there are a total of 100 heart attack patients out of which 20 suffer from depression and 80 constitutes others who do not suffer from depression after a heart attack.

Now, out of the remaining 80, let us assume 30% (equaling 24 persons) are likely to need hospital care for a heart problem again within a year. Going by the info given in the question, out of the 20 who suffered from depression, 85% (55% more likely than others equaling 17 persons) will be needing hospital care for a heart problem again within a year.

In this case, out of the 41 rehospitalised people, it is very likely that they are not suffering from depression rather than suffering from depression (As 24 > 17).

So B is ruled out.

E looks plausible.
