Columnist: Analysts argue that as baby boomers reach the age of 50, they will begin seriously planning for retiremen...

@zacharydtan,

Happy to help.

(A) says, "attempts to undermine the analysts' argument by questioning
the truth of its premises"

The problem with (A) is that the author actually agrees that baby
boomers will eventually become savers, so there is not a disagreement
with the truth of the analyst's premises. Thus, we can get rid of (A).

(C) says, "attempts to undermine the analysts' argument by drawing an
alternative conclusion from the analysts' premises"

The author's conclusion disagrees with the conclusion of the analysts.
The author's premises, however, are the same (baby boomers will
eventually become savers). From this, we know that this is an instance
of coming up with an alternative/different conclusion from the same
set of premises. Thus, (C) is the correct answer.

Does this make sense? Let us know if you have any other questions!
