When this question was posted by Paul I think, I also answered (E) but the answer correctly is (C). I don't have the link, but will try to explain it here.
(E) says, companies listed on NASDAQ are not listed on DOW Jones. Now this might not be the case, some companies listed on NASDAQ, might be listed on DOW Jones, but overall DOW Jones other major shares (On which the index value really depends) are doing bad then this won't help.
On the Other cosider (C).
If NASDAQ lists companies that are performing badly then the index value itself will decline and then the statement "E-Business ....takeover...." will fall apart.
Let me know if this is of any help!!
Else will try to come up with something else.
