can someone help please! i almost got this wrong.

I was stuck between C and E.

C was attractive to me because it said " she suspects that it will be highly desirable to other collectors in the future".

In my diagram I had B> A + D + /I. The Contrapositive is I or /D or /A > /B.

SO: Wouldn't answer choice "C" be correct as well? Since the last sentence shows it meeting the investment aspect, therefore don't buy?

can someone explain to me the sherlock holmes question regarding the first sentence "any" and "when"? I put the any in the sufficient because i thought the "when" was a necessary indicator.
