what if a and c/d/e are negative instead of a and b. then first term would not be true right?

I think you have forgotten that the stem says $$a<b<c<d<e$$ and $$abcde > 0$$

so $$b$$ cannot be $$+ve$$ and each of $$a, c, d$$ and $$e$$ be -ve

Imagine a number line. If b is $$+ve$$ then everything to the right of $$b$$ has to be greater than $$b$$. So how can $$c, d$$ and $$e$$ be $$-ve$$?

Hence the condition that you have chosen is not allowed according to the question.

Hope it's clear now.

Let me know if anything is still unclear.
