@Julie-V,

Let's look at (C) and (D).

(C) says, "Sales of computers for home use will never reach the levels
optimistically projected by manufacturers. The reason is that home use
was envisioned as encompassing tasks, such as menu planning and
checkbook reconciliation, that most homemakers perform in much simpler
ways than using a computer would require."

(C)'s conclusion is quite similar to the one in the stimulus (that
computer use will not be as big as predicted). However, while the
stimulus mentions computer sales as a premise, (C) discusses the ways
people prefer doing things, so this is quite a bit different. Thus, we
can get rid of (C).

(D) says, "It is apparent that consumers have tired of microwave ovens
as quickly as they initially came to accept this recent invention. In
contrast to several years of increasing sales following the
introduction of microwave ovens, sales of microwave ovens flattened
last year, indicating that consumers have found relatively little use
for these devices."

(D) is equivocating between sales and use, just as the stimulus does.
(D) is saying that microwave sales have flattened and this shows that
people have little use for them, but it's totally possible that almost
everyone has already bought a microwave and is using the one they
bought, so they don't' need to go out and buy a new one. Thus, (D)
mirrors the flawed reasoning of the stimulus really well and is the
correct answer choice.

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