GMAT Critical Reasoning (CR) | Re: Previously, Autoco designed all of its cars itself and then contracted

E.

Was between C and E however if you think C in more detail you will see that if the other costs actually increase, then it will not be able to support the expectation.

Lets say if it was 60% outside supplier and the rest is other costs. If 60% of it went down, there is nothing to say that the rest of the cost stays the same.

E takes a safer route and doesn't allow for such an assumption and that bet pays off
