Data Sufficiency

(1) c = 1 and cde = 24

(2) d/c = 4 and d/e= 2/3

It really comes down to whether or not "one-digit number" implies that the numbers (c, d and e) are strictly positive or they can be positive or negative.

If they can be positive or negative, then statement 2 is not sufficient (the rationale for this is well explained by other posters). If "one-digit number" implies that the numbers are strictly positive, then statement 2 is sufficient.

It might be useful to go to the OG12 for an answer. First, there's nothing in the math review section that indicates whether or not "one-digit number" implies that the number is strictly positive.

However, if we examine PS question #182 in the OG12, we are told that "... the two-digit integers M and N are positive..."

Since the OG12 makes a point of mentioning that M and N are positive, I think we can assume that, if this condition of positiveness were not added, then M and N could be either positive or negative.

So, going back to the original question, it seems that c, d and e can be either positive or negative.
As such, I believe the answer is C
